			<content:encoded><![CDATA[<p><a href="http://venturebeat.com/2012/05/10/cloud-services-data/" target="_blank">Cloud Perceived as Precarious by Companies</a><br />
Cloudability study of 3,200 companies relying on the cloud, showed that 86% of them rely on 2 or more cloud solutions.</p>
<p><a href="http://blog.mozilla.org/blog/2012/05/09/windows-on-arm-users-need-browser-choice-too/" target="_blank">Will IE10 have a Monopoly on Windows RT (ARM processor)? </a><br />
Mozilla&#8217;s general counsel writes about the limitations browsers are facing with the new Windows 8 RT and how IE is the only browser that can run on native mode in this platform.</p>
<p><a href="http://www.netmagazine.com/news/ie9-bucks-microsoft-browser-trends-121952" target="_blank">IE9 – Not Just For Work </a><br />
We previously reported on Chrome usage spiking during the weekend in our Browser Wars updates. Now, StatCounter, is reporting that IE9 usage spikes on the weekend as well, showing that IE is making a comeback as a “play-time” browser with their latest release.</p>
<p><a href="http://lastdropofink.co.uk/personal/random-stuff/facebook-like-button-84kb-or-1340-seconds/" target="_blank">That Widget Might Cost your Webpage 1.34 Seconds </a><br />
Think twice before adding a widget to you page. The author of this blog article discovers that the Facebook widget on the page is adding 84KB of data and 1.34 seconds to the load time.</p>
<p><a href="http://gigaom.com/cloud/adventures-in-big-data-how-addthis-hydra-works" target="_blank">Hydra: Big data at AddThis</a><br />
AddThis handles 3 billion visits a day, resulting in 10 terabytes of data. Hydra is their real time analytics solutions which relies on custom-built distributed file system to store the data</p>
<p><a href="http://searchenterprisewan.techtarget.com/news/2240149781/Interop-2012-Mobile-application-delivery-improved-with-SPDY-protocol " target="_blank">F5 Load Balancer Now Supports SPDY </a><br />
F5 announced first-to-market Mobile Application Optimization with SPDY support at Interop 2012. The goal is to improve mobile browsing experience by delivering content more efficiently and improving webpage rendering. This is an update to their Application Delivery Control, which now supports SPDY for browsers/clients that have incorporated the protocol.</p>
<p><a href="http://www.news24.com/SciTech/News/Facebook-takes-step-into-cloud-storage-20120511" target="_blank">Facebook Now Offers Cloud Storage </a><br />
Right before the IPO, Facebook announces that they are now dabbling with cloud storage with the release of a new feature that allows groups of users to share a file. This puts Facebook in competition with other storage services such as Apple and Dropbox.</p>
<p><a href="http://www.technologyreview.com/blog/arxiv/27843/" target="_blank">From China: Teleportation for Data Security </a><br />
Physicists in China have been able to teleport entangled protons the longest distance yet – 97kilometers. While this is cool for whatever Sci-Fi fantasy you may have, the current focus is on the possibilities of satellite-based quantum cryptography, which could provide the most secure connections yet.</p>

			<content:encoded><![CDATA[<p style="text-align: center;"><img class="alignnone size-medium wp-image-2583" title="Congratulations Home Depot" src="http://blog.catchpoint.com/wp-content/uploads/2012/02/applause.jpg?w=300" alt="Congratulations Home Depot" width="300" height="114" /></p>
<p> <a href="http://www.crateandbarrel.com/">Crate and Barrel</a> joins <a href="http://blog.catchpoint.com/2012/02/14/homedepot-perflif/">The Home Depot</a> and <a href="http://blog.catchpoint.com/2012/04/17/lemonde-perflif/">Le Monde</a> in the elite group of companies that is actively working on improving web performance, to provide better end user experience and ultimately, improve their bottom line.</p>
<p>Back in 2011, <a href="http://blog.catchpoint.com/2012/01/05/holiday-shopping-2011-state-of-retail-web-performance/">we compared the website performance of the top Internet Retailer websites</a> during the shopping season. Crate and Barrel did not do well in the study but instead of being angry at us, they called me and we had an amazing discussion about what went wrong.</p>
<p>This past week, I received another call from the Crate and Barrel team. “Hey Mehdi, we have been working on our performance and wanted to get your feedback!” I was shocked by the changes they had implemented. As I was charting their data for the last 6 months the first word that came to mind was “<strong>Beautiful</strong>”.</p>
<p>After the close of the holiday season, the Business and IT team at Crate and Barrel decided to make web performance a key priority for 2012 and I believe they are going to do very well this year.</p>
<p>Without any further interruptions here are the results:</p>
<ul>
<li>The time to Document Complete (or onload) improved by more than <strong>49%</strong></li>
<li>The Total Page Load time improved by more than <strong>39%</strong></li>
</ul>
<p>Here are performance measurements before and after the &#8220;Perflift&#8221; from 10 US nodes since Nov 2011.</p>
<p><span id="more-2887"></span></p>
<div id="attachment_2889" class="wp-caption aligncenter" style="width: 650px"><a href="http://blog.catchpoint.com/2012/05/08/crateandbarrel-perflift/cratebarrel-performancehistorical/" rel="attachment wp-att-2889"><img class="size-large wp-image-2889" title="Crate &amp; Barrel Historical Web Performance Data" src="http://blog.catchpoint.com/wp-content/uploads/2012/04/cratebarrel-performancehistorical-1024x454.jpg" alt="Crate &amp; Barrel Historical Web Performance Data" width="640" height="283" /></a><p class="wp-caption-text">Crate &amp; Barrel Historical Web Performance Data</p></div>
<p>I picked a few dates to highlight the improvements:</p>
<div id="attachment_2890" class="wp-caption aligncenter" style="width: 528px"><a href="http://blog.catchpoint.com/2012/05/08/crateandbarrel-perflift/cratebarrel-keymetricsovertime/" rel="attachment wp-att-2890"><img class=" wp-image-2890 " title="Crate &amp; Barrel Web Performance Improvments" src="http://blog.catchpoint.com/wp-content/uploads/2012/04/cratebarrel-keymetricsovertime.jpg" alt="Crate &amp; Barrel Web Performance Improvments" width="518" height="326" /></a><p class="wp-caption-text">Document Complete and Web Page Response</p></div>
<p>From a WPO (Web Performance Optimization) perspective the engineering team did a fantastic job at:</p>
<ul>
<li>Combining images with CSS sprites</li>
<li>Reducing the number of third party tags, and loading the tags after document complete.</li>
<li>Adding proper expiration headers to assets</li>
<li>Relying on &#8220;Text&#8221; in place of images when possible</li>
<li>Minification of JS and CSS files</li>
</ul>
<div id="attachment_2891" class="wp-caption aligncenter" style="width: 372px"><a href="http://blog.catchpoint.com/2012/05/08/crateandbarrel-perflift/cratebarrel-wpo1/" rel="attachment wp-att-2891"><img class=" wp-image-2891 " title="Crate and Barrel Web Performance Optimization" src="http://blog.catchpoint.com/wp-content/uploads/2012/04/cratebarrel-wpo1.jpg" alt="Crate and Barrel Web Performance Optimization" width="362" height="368" /></a><p class="wp-caption-text">Crate and Barrel Web Performance Optimization</p></div>
<p>The total downloaded bytes was cut in half:</p>
<div id="attachment_2892" class="wp-caption aligncenter" style="width: 363px"><a href="http://blog.catchpoint.com/2012/05/08/crateandbarrel-perflift/cratebarrel-wpo2/" rel="attachment wp-att-2892"><img class=" wp-image-2892  " title="Crate and Barrel WPO Downloaded Bytes " src="http://blog.catchpoint.com/wp-content/uploads/2012/04/cratebarrel-wpo2.jpg" alt="Crate and Barrel WPO Downloaded Bytes " width="353" height="221" /></a><p class="wp-caption-text">Crate and Barrel WPO Downloaded Bytes</p></div>
<div id="attachment_2894" class="wp-caption aligncenter" style="width: 303px"><a href="http://blog.catchpoint.com/2012/05/08/crateandbarrel-perflift/cratebarrel-wpo3-2/" rel="attachment wp-att-2894"><img class=" wp-image-2894  " title="Crate and Barrel WPO Content Changes" src="http://blog.catchpoint.com/wp-content/uploads/2012/04/cratebarrel-wpo31.jpg" alt="Crate and Barrel WPO Content Changes" width="293" height="368" /></a><p class="wp-caption-text">Crate and Barrel WPO Content Changes</p></div>
<p>I hear that the team is not done yet! I look forward to Crate and Barrel ranking very high in 2012 Shopping Season.</p>
<p>Congratulations to the entire Crate and Barrel Team for pulling off this “<strong>Perflift</strong>” (think Facelift, a rejuvenating SPA for website) successfully! Companies from around the world should take a close look and learn from Crate and Barrel, Le Monde and The Home Depot.</p>
<p>Mehdi – Catchpoint</p>

			<content:encoded><![CDATA[<p><a href=" http://gigaom.com/2012/05/03/ebay-puts-down-roots-in-nyc-with-data-focused-tech-center" target="_blank">Ebay Expanding on East Coast</a><br />
New York City is getting another tech giant tenant – Ebay recently secured a 35,000 sq ft space for a new development space in Manhattan. They are following in the footsteps of Google, Facebook, and Twitter and are hoping to tap into the growing pool of East coast talent. Ebay is planning on opening its new office in the fall.</p>
<p><a href="http://news.cnet.com/8301-1023_3-57424595-93/ie-continues-to-rebound-in-browser-market/" target="_blank">Browser Wars Continue</a><br />
Conflicting reports are out by two analytic companies regarding the IE rebound driven by the new release of IE9. Net Applications, which accounted for geographical usage patterns, daily usage, pre-rendered pages, and its own analytics into the analysis, reports that IE usage grew from 53.8% in March to 54.1% in April. StatCounter, using a different methodology in which they only count raw page views, reports that IE is still continuing to slide while Chrome keeps on gaining momentum.</p>
<p><a href="http://techcrunch.com/2012/04/30/akamai-global-average-connection-speed-dropped-14-in-q4-2011-down-5-3-in-u-s/" target="_blank">Connection Speed Dropped in 8 of 10 Top Countries</a><br />
Akamai&#8217;s most recent <a href="http://www.akamai.com/stateoftheinternet/" target="_blank">State of the Internet report</a> shows that the global connection speed at the end of 2011 had dropped 14% from the previous quarter to 2.3 Mbps.  The US (ranked no. 13) connection speed fell 5.3% to 5.87 Mbps.</p>
<p><a href="http://adactio.com/journal/5439/" target="_blank">Optimizing Images for Mobile and Web</a><br />
Jeremy Keith shares his tricks for optimizing the dConstruct conference website – including serving monochromatic images and focusing only on faces on pictures.</p>
<p><a href="http://searchsoftwarequality.techtarget.com/news/2240149496/Application-performance-management-tools-A-must-have-for-the-cloud" target="_blank">Push for Cloud Means More APM</a><br />
As more companies are adopting the cloud as an infrastructure solution, there is a push in the Application Performance Management (APM) market to evolve to offer the visibility into the cloud that companies now have a need for.  Traditional and in-house APM solutions may no longer be enough to provide the insight needed to take control.</p>
<p><a href="http://blogs.msdn.com/b/ieinternals/archive/2012/05/05/problems-with-using-img-to-prefetch-script-or-css.aspx" target="_blank">Relying on a Browser Hack? Make sure you test well and keep on testing.</a><br />
One trick web developers use to pre-cache resources is to pre-fetch JavaScript and CSS files by relying on the &lt;img&gt; tag.  Eric Law of Microsoft clearly describes why this &#8220;hack&#8221; will not work and results in &#8220;request aborts&#8221;, resulting in slower webpage loads. The solution will not work on IE6 to 10 and Firefox 12.</p>

The challenge to determine the size of Amazon Web Services is still on and here is the latest prediction – 1 -2 billion dollars a year in revenue.   Can anyone guess the profits?</p>
<p><a href="http://www.datacenterknowledge.com/archives/2012/04/27/choosing-a-data-center-colocation-site/" target="_blank">Colocation Check List</a><br />
Choosing a colocation site?  Here are a couple ‘out of the box’ questions to have on hand during the decision process.</p>

Using tricks from news feed implementation (delivering results of complex queries fast), engineers at Facebook built a real time internal infrastructure monitoring system capable of fast ad hoc analysis – delivering results that scanned hundreds of millions of samples in less than 1 second.</p>
<p><a href="http://www.bbc.com/news/technology-17811557" target="_blank">Who knew? JPEG uses less energy on your phone than GIF or PNG</a><br />
Stanford researchers at the World Wide Web 2012 Conference presented data showing how free applications and top websites, even ones optimized for mobile, kill your smartphone’s battery. Energy consumption can be blamed mostly on advertising and browser downloading and parsing of Javascript and CSS.</p>

The CTO of Blekko, a new spam-free search engine, describes the requirements it takes to build a search engine and datastore, including hardware and software options.  Using a new construct called Combinators, Blekko is able to manipulate data in the single cell level, instead of locking an entire row in as traditional NoSQL database.</p>

<p>&nbsp;</p>
<p>A month ago, we wrote about how the <a href="http://www.homedepot.com">Home Depot</a> improved their <a href="http://blog.catchpoint.com/2012/02/14/homedepot-perflif/">web performance through a major &#8220;Perflift&#8221;</a>. Today, we want to congratulate &#8220;l’equipe&#8221; at <a href="http://www.lemonde.fr">Le Monde</a> for improving their website.</p>
<p>While The New York Times is the number one newspaper in US, Le Monde is the number one news source in France and for French speakers around the world. I have a deep and personal relationship with Le Monde; as it allowed me to stay informed while travelling around the world before settling in the US. I continue to be an online subscriber not only to have a deeper world news coverage but also to practice my French.</p>
<p>This year Le Monde&#8217;s IT team embarked on a major project to make the website faster. The key business driver was to increase web traffic by providing the best user experience. The development team rebuilt several parts of their system from scratch and optimized the front end code to achieve their performance goals. As part of the initiative, they modified how third party tags are rendered on the page in order to minimize their performance exposure and risks. This &#8220;Perflift&#8221; has a big payoff for the end users and the company as the new website blows away the old site in performance:</p>
<ul>
<li>The time to Document Complete (or onload) improved by more than 50%</li>
<li>The Total Page Load time improved by more than 33%</li>
</ul>
<p>Here are performance measurements before and after the &#8220;Perflift&#8221; from 5 European nodes (Paris, London, Amsterdam, Frankfurt, Milan)</p>

<p>&nbsp;</p>
<p>From a WPO (Web Performance Optimization) perspective the Le Monde engineering team did a fantastic job at:</p>
<ul>
<li>Reducing the number of CSS files</li>
<li>Serving static content from cookie-less domains,</li>
<li>Relying on CSS Sprites</li>
<li>Domain sharding</li>
<li>Loading the ads post document complete.</li>
<li>Most importantly, loading JS asynchronously. They went from 700Kb to 100Kb of sync/blocking JS on the Home Page!</li>
<li>Loading images asynchronously, triggering image load on user scrolling.</li>
</ul>
<div id="attachment_2863" class="wp-caption aligncenter" style="width: 490px"><a href="http://blog.catchpoint.com/2012/04/17/lemonde-perflif/lemonde-beforeafter-content/" rel="attachment wp-att-2863"><img class=" wp-image-2863 " title="Le Monde Web Performance - Content Before &amp; After" src="http://blog.catchpoint.com/wp-content/uploads/2012/04/Lemonde-beforeafter-content.jpg" alt="Le Monde Web Performance - Content Before &amp; After" width="480" height="268" /></a><p class="wp-caption-text">Le Monde Web Performance - Content Before &amp; After</p></div>
<p>We hear that they have a few more tricks up their sleeves they plan to implement in order to keep improving the site speed.</p>
<p>Congratulations to the entire Le Monde Team for pulling off this “Perflift” successfully! Companies from around the world should take a close look and learn from Le Monde and Home Depot.</p>
<p>Bravo! Cocorico!</p>

Eighteen months ago Google launched the False Start feature on Chrome to speed up the SSL handshake by as much as 30%. However, Google is now retiring the feature with Chrome 20 as it caused unavailability for several websites. Although Google tried to tackle the problem on several fronts it was unable to find a solid solution. The biggest challenge was legacy code in SSL Terminators, especially for international website.</p>

Traditionally, cloud computing platforms offered either a choice between old technology, low-cost public storage and more expensive, higher performance private clouds. Now, as buyers are wising up to performance impacts on revenue, there is a push in the market for solutions that offer a high availability, secure alternative for the smaller consumer. This hybrid cloud demand will drive up the cost of low-end solutions up.</p>

As more and more people rely on richer web applications for entertainment and communication, network latency has a bigger impact on the home user. However for the typical user, unlike someone on trading networks on Wall Street, one cannot simply ask their provider for a better connection. Luckily, new products are development that help manage the consumer’s network &#8211; such as setting priority to certain packets that need to be delivered faster.</p>

			<content:encoded><![CDATA[<p><em>This is a guest post courtesy of <a href="https://twitter.com/#!/jedisct1" target="_blank">Frank Denis</a>. The post originally appeared on <a href="http://00f.net/2011/11/17/how-long-does-a-dns-ttl-last/" target="_blank">Frank&#8217;s personal blog</a> on November 17th, 2011.</em></p>
<p>In a DNS zone, every record carries its own time-to-live, so that it can be cached, yet still changed if necessary.</p>
<p>This information is originally served by authoritative servers for the related zone. The TTL is represented as an integer number of seconds.</p>
<p>At first sight, the mechanism looks straightforward: if the www.example.com record has a TTL of 30, it&#8217;s only valid up to 30 second, and caches must fetch it again if requested after this delay.</p>
<h2>Chained caches</h2>
<p>DNS caches can be chained: instead of directly querying authoritative servers, a cache can forward queries to a another server, and cache the result.</p>
<p>Having 3 or 4 chained caches is actually very common. Web browsers, operating systems and routers can cache and forward DNS a query. Eventually, this query will be sent to an upstream cache, like the ISP cache or a third-party service like <span style="color: #008000;"><em>OpenDNS</em></span>. And these caches can also actually hide multiple chained caches.</p>
<p>In order to respect the original TTL, caches are modifying records as they forward them to clients. The response to a query that has been sitting in a cache for 10 second will be served with a TTL reduced by 10 second. That way, if the original TTL was 30 second, the whole chain is guaranteed to consider this record as expired as the same time: the original meaning of the TTL is retained no matter how many resolvers there are in the way.</p>
<p>Well, not exactly. A TTL is just a time interval, not an absolute date. Unlike a HTTP response, a DNS response doesn&#8217;t contain any timestamp. Thus, requests processing and network latency are causing caches to keep a record longer than they actually should in order to respect the initial TTL.</p>
<p>A TTL being an integer value makes things even worse: a chain of <strong><span style="color: #993300;">N</span></strong> caches can introduce a <strong><span style="color: #993300;">N</span></strong> second bias.</p>
<p>In practice, this is rarely an issue: TTLs as served by authoritative servers are considered indicative, and not as something to depend on when accurate timing is required.<span id="more-2819"></span></p>
<h2>The decay of a TTL, as seen by different pieces of software</h2>
<p>How does the TTL of a record served by a DNS cache decays over time?</p>
<p>Surprisingly, different implementations exhibit different behaviors.</p>
<p>For a record initially served with a TTL equal to <span style="color: #993300;">N</span> by authoritative servers:</p>
<ul>
<li><span style="color: #008000;"><em>Google DNS</em></span> serves it with a TTL in the interval <span style="color: #993300;">[0, N-1]</span></li>
<li><span style="color: #008000;"><em>dnscache</em></span> is serving it with a TTL in the interval <span style="color: #993300;">[0, N]</span></li>
<li><span style="color: #008000;"><em>Unbound</em></span> serves it with a TTL in the interval <span style="color: #993300;">[0, N]</span></li>
<li><span style="color: #008000;"><em>Bind</em></span> serves it with a TTL in the interval <span style="color: #993300;">[1, N]</span></li>
<li><span style="color: #008000;"><em>PowerDNS</em></span> Recursor always serves it with a TTL of <span style="color: #993300;">N</span></li>
</ul>
<p>Hold on&#8230; Does it mean that how frequently an entry will actually be refreshed depends on what software resolvers are running?</p>
<p>Sadly, yes. Given a record with a TTL equal to <span style="color: #993300;">N</span>:</p>
<ul>
<li><em><span style="color: #008000;">Bind</span></em> and <em><span style="color: #008000;">PowerDNS Recursor</span></em> refresh it every <span style="color: #993300;">N</span> second if necessary</li>
<li><em><span style="color: #008000;">Unbound</span></em> and <em><span style="color: #008000;">dnscache</span></em> are only refreshing it every <span style="color: #993300;">N + 1</span> seconds at best.</li>
</ul>
<h2>TTL Zero</h2>
<p>Although a <a href="http://mark.lindsey.name/2009/03/never-use-dns-ttl-of-zero-0.html" target="_blank">TTL of zero can cause interoperability issues</a>, most DNS caches are considering records with a TTL of zero as records that should not be cached.</p>
<p>This perfectly makes sense when the TTL of zero is the original TTL, as served by authoritative servers.</p>
<p>However, when a cache artificially changes the TTL to zero, it changes a record that had been designed for being cached to an uncachable record that contaminates the rest of the chain.</p>
<h2>dnscache and a 1 second record</h2>
<p>To illustrate this, a Linux box has been setup with a local DNS cache. <em><span style="color: #008000;">Unbound</span></em> has been chosen, but the last component of the chain actually makes little difference. Even web browsers caches have a very similar behavior.</p>
<p>Queries are forwarded to an upstream cache on the same LAN, running <em><span style="color: #008000;">dnscache</span></em>, and outgoing queries are recorded with ngrep. The same query, whose response has a TTL of <span style="color: #993300;">1</span>, is made at a 10 queries per second rate.</p>
<p>The <span style="color: #993300;">X</span> axis represents outgoing queries, whereas the <span style="color: #993300;">Y</span> axis is the time elapsed since the previous query.</p>
<p><a href="http://blog.catchpoint.com/2012/04/04/dns-records-and-ttl-how-long-does-a-second-actually-last/unbound-djbdns-one1/" rel="attachment wp-att-2820"><img class="aligncenter size-full wp-image-2820" title="Unbound DNS - DNS TTL of 1" src="http://blog.catchpoint.com/wp-content/uploads/2012/04/unbound-djbdns-one1.jpg" alt="" width="640" height="343" /></a></p>
<p>Even though a TTL of <span style="color: #993300;">1</span> is served by authoritative servers for this record, a large amount of responses are cached and served for <span style="color: #993300;">2</span> second. This is due to the local <em><span style="color: #008000;">Unbound</span></em> resolver.</p>
<p>However, there is also quite a lot of responses that haven&#8217;t been cached at all. It happens when <em><span style="color: #008000;">dnscache</span></em> serves a response with a TTL of <span style="color: #993300;">0</span>. Since it happens one third of the time, this is suboptimal and not on par with the intent of the authoritate record, which is served with non-zero TTL.</p>
<p>And although <span style="color: #008000;"><em>dnscache</em></span> and <span style="color: #008000;"><em>Unbound</em></span> are handling TTLs the same way, we can&#8217;t expect their caches to be perfectly synchronized. When the local cache considers a record as expired and issues an outgoing query, the upstream server can consider it as not expired yet, just in the middle of the last second. What we get is a constant race between caches, causing jitter and outgoing queries sent after 1 second.</p>
<h2>How different implementations can affect the number of outgoing queries</h2>
<p>The following experiment has been made by observing outgoing queries when sending <span style="color: #993300;">10,000 queries for a record with a TTL of 2</span>, at an average 10 qps rate, to a local cache, using Google, OpenDNS and Level 3 as upstream resolvers.</p>
<p>Here is the number of outgoing queries that were required to complete the <span style="color: #993300;">10,000 local queries</span> using different services:</p>
<table style="width: 400px;">
<tbody>
<tr>
<th><span style="color: #993300;">Service</span></th>
<th><span style="color: #993300;">Outgoing queries</span></th>
</tr>
<tr>
<td>Google DNS</td>
<td>1383</td>
</tr>
<tr>
<td>OpenDNS</td>
<td>632</td>
</tr>
<tr>
<td>Level 3</td>
<td>388</td>
</tr>
</tbody>
</table>
<p><a href="http://blog.catchpoint.com/2012/04/04/dns-records-and-ttl-how-long-does-a-second-actually-last/unbound-remote1/" rel="attachment wp-att-2821"><img class="aligncenter size-full wp-image-2821" title="DNS Queries on Google, OpenDNS, Level 3" src="http://blog.catchpoint.com/wp-content/uploads/2012/04/unbound-remote1.jpg" alt="" width="640" height="343" /></a></p>
<p>&nbsp;</p>
<p>When using <span style="color: #008000;"><em>Google DNS</em></span> (blue dots), queries are effectively never cached more than <span style="color: #993300;">2 second</span>, even locally. This is due to the max TTL returned by <span style="color: #008000;"><em>Google DNS</em></span> being the initial TTL <span style="color: #993300;">minus one</span>.</p>
<p>When <span style="color: #008000;"><em>Google DNS</em></span> returns a TTL of<span style="color: #993300;"> zero</span>, we observe the same jitter and the same slew of queries that couldn&#8217;t be served from the local cache.</p>
<p><em>OpenDNS</em> (orange dots) has the same behavior as <span style="color: #008000;"><em>dnscache</em></span> and <span style="color: #008000;"><em>Unbound</em></span>, with TTLs in the <span style="color: #993300;">[0, N]</span> interval. Our initial TTL with a value of <span style="color: #993300;">2</span> actually causes <span style="color: #993300;">3, 2, and 1 second delays</span> between request, plus a sensitive amount of consecutive outgoing queries due a null TTL.</p>
<p style="padding-left: 30px;"><span style="color: #993300;"><strong>Note:</strong></span> Since the original post <span style="color: #008000;"><em>OpenDNS</em></span> resolvers have been updated to behave like Bind: TTLs are in the<span style="color: #993300;"> [1, N]</span> interval.</p>
<p><span style="color: #008000;"><em>Level 3</em></span> (green dots) is running <span style="color: #008000;"><em>Bind</em></span>, which returns a TTL in the <span style="color: #993300;">[1, N]</span> interval. <span style="color: #008000;"><em>Bind</em></span> caches records<span style="color: #993300;"> one second less</span> than <span style="color: #008000;"><em>dnscache</em></span> and <span style="color: #008000;"><em>Unbound</em></span>. Because our local resolver is <span style="color: #008000;"><em>Unbound</em></span>, queries received with a TTL of<span style="color: #993300;"> N</span> are actually cached N + 1 second. But as expected, the frequency of required outgoing queries very rarely exceeds 3 second.</p>
<p>What the correct behavior is, is out of scope of this article. All major implementations are probably correct.</p>
<p>But from a user perspective, with only <span style="color: #993300;">2</span> caches in the chain, and for a given record, the same set of queries can require <span style="color: #993300;">up to 3.5 more outgoing queries</span> to get resolved, depending on what software the remote cache is running.</p>
<p>With CDNs and popular web sites having records with a very low TTL (Facebook has a 30 second TTL, Skyrock has a 10 second TTL), the way a cache handles TTLs can have a sensible impact on performance. That said, some resolvers can be configured to pre-fetch records before they expire, effectively mitigating this problem.</p>
<h2>The OSX cache</h2>
<p><span style="color: #008000;"><em>MacOS X</em></span> provides a system-wide name cache, which is enabled by default.</p>
<p>Its behavior is quite surprising, though. It seems to enforce<span style="color: #993300;"> a minimum TTL of 12.5 seconds</span>, while still requiring some outgoing queries delayed by the initial TTL value, and some consecutive ones. Resolving the <span style="color: #993300;">10,000 queries</span> from the previous test took only an average of <span style="color: #993300;">232 outgoing queries</span>.</p>
<p>Using <span style="color: #008000;"><em>Google DNS</em></span>, <span style="color: #008000;"><em>OpenDNS</em></span> and <span style="color: #008000;"><em>Level 3</em></span> as a remote resolver produce the same result, with the exception on <span style="color: #008000;"><em>Level 3 (Bind)</em></span> avoiding frequent (less than 1 sec) consecutive queries during the time other return a TTL of zero.</p>

			<content:encoded><![CDATA[<p><em>This is a guest post courtesy of </em><a href="http://www.twitter.com/tomdyninc"><em>Dyn CTO Tom Daly</em></a><em>.</em></p>
<p>At Dyn, we obsess about network performance and the proof is in the tools we have built over the years to constantly monitor how our network is running. With a globally deployed <a href="http://dyn.com/dns/network-map/"><strong>Anycast DNS</strong></a> network, constant internal and external monitoring of our performance is critical. This constant surveillance of our network ensures that we keep providing top-notch services. One of the biggest challenges is being at the mercy of third party providers and their monitoring platforms when monitoring our Anycast network.</p>
<p>After all, we cannot monitor ourselves and be fully objective with the data.</p>
<p>One of the issues with using external monitoring providers has always been the ability to pull data from the monitoring provider within an acceptable interval. We really want to be seeing data within a few seconds of a test run completing so that we can correct any issue just as soon as it happens. For a long time, we’ve been working with monitoring providers that can get us our data in five or ten minutes at minimum and on a dashboard they render – hardly usable for our operations.<span id="more-2773"></span></p>
<p>As we’ve mentioned before, one of our favorite monitoring providers is <a href="http://www.catchpoint.com/">Catchpoint</a> and thanks to their Data Push API, we’re able to receive a constant stream of feedback from their 50 global monitoring nodes in real time. Every five minutes, a Catchpoint node performs a series of tests against our DNS servers and instantaneously relays that information to the central Catchpoint collector, but also ships a copy of the results to a webserver on our network so we can begin reviewing those results immediately.</p>
<p>Enter the challenging part: how do we build a dashboard with ACTIONABLE data with 50 data sources and 4 targets (over 200 data points) over an hour’s time? Enter Alex Sergeyev from our <a href="http://www.dyn.com/labs">Dyn Labs</a> team, some ZeroMQ love and work with Websockets and D3.js. Alex built us a very slick visualization application that allows us to really see what’s happening in real time.</p>
<p><strong>The design of the perfect dashboard</strong></p>
<p>We decided to create a system to deliver the stream of data from Catchpoint API down to all connected web-browsers in forms of 50+ little charts. In the past, we have been shipping the data to a Graphite server as well, so we wanted to keep that running too.</p>
<p>We built three parts of the system to scale them independently as needed:</p>
<ul>
<li>Catchpoint API receiver that analyses data and sends simple parsed lines to ZeroMQ PUB socket.</li>
<li>Websockets server that receives data from a ZeroMQ SUB socket and also keeps keeps state of last probes per monitoring node in a memory-mapped file (for some flavor of persistence across restarts).</li>
<li>A Graphite “shovel” which also receives data from the same ZeroMQ SUB socket and sends results to a Graphite server.</li>
</ul>
<p>We used Perl for both of the web services parts, because it gives us a way to code simple applications very fast. Both web services were implemented as simple AnyEvent servers.The design above allows us to have sub 100ms latency between receiving data from monitoring nodes and sending it out to a connected web sockets.</p>
<p>After building out the backend, most of the development time was spent to create visual representation of the data we got. We wanted to be flexible with our view and decided to use D3.js to help us with that. It’s an amazing tool which allows to make truly data-driven visualizations. We started from simple line/area charts to emulate visualizations that we are used to look at in Graphite and RRD based tools. We even wrote a SmokePing emulation library for D3.js, used it for our dashboard and plan to release it via our <a href="https://github.com/dyninc">GitHub page</a> in the future.</p>
<p>Here are few examples of charts that it generates (dashboard size):</p>
<div id="attachment_2775" class="wp-caption aligncenter" style="width: 460px"><a href="http://blog.catchpoint.com/2012/03/27/on-the-journey-for-the-perfect-network-health-dashboard/smokeping_dashboard_widget_d3js/" rel="attachment wp-att-2775"><img class=" wp-image-2775 " title="Smokeping Dashboard WidgetD3.js" src="http://blog.catchpoint.com/wp-content/uploads/2012/03/Smokeping_Dashboard_Widget_D3js-300x26.png" alt="Smokeping Dashboard WidgetD3.js" width="450" height="39" /></a><p class="wp-caption-text">Smokeping Dashboard WidgetD3.js</p></div>
<p>Taking these basic charts and the smarts of our UX genius <a href="http://dyn.com/author/lara/">Lara Swanson</a>, we transformed boring sets of 50 charts on a page to a display that ended up looking neat and pretty on either laptop screen or Internet TVs around the office. We decided to group charts by monitoring region and sort each section (credits to D3.js for making it simple) by mean response time, plus twice of standard deviation to “promote” trouble spots to the front of each grouping dynamically to make the data actionable!</p>
<p>Our current dashboard is not quite final but we’re proud of what we quickly built:</p>
<ul>
<li>a scalable sub 100ms data publishing system that kept our existing Graphite integration working and added our new dashboards.</li>
<li>a simple, dynamic view of all available data (over twenty thousand data points) aggregated to help us know if there are any regional or local issues affecting the quality of our DNS services.</li>
<li>an easy spot for our capacity planning and P&amp;O engineers to look at when they are looking to make improvements to the network.</li>
</ul>

<p>February came and went so fast we forgot to give you a quick update on what we have been up to!</p>
<h2><span style="color: #006cb1;">Empowering Data Analysis</span></h2>
<p>Our in house NoSQL/In-Memory reporting platform allows customers to run statistical analysis of the data in real time and it stores historical data for 2 years+ since the first day of the launch. However,  it had one limitation &#8211; customers could not chart and report at the 5 minute breakdown past the last 40 days. Well no more!</p>
<p>Last December, our engineering team embarked on a big project to enhance our backend systems and unleash the stored data to Catchpoint end users. Our data warehouse already stored the data we needed, however, we had to drastically change how data was stored and rewrite the report service to properly access and process it.</p>
<p>Starting this week Catchpoint customers are able to chart up to the 5 minute interval and even chart a scatter plot at the minute level on historical data going back 2 years. Yes, they can even chart a scatter plot from the data collected in 2010!</p>
<h2><span style="color: #006cb1;">Mobile Playback:</span></h2>
<p>Customers can now test the mobile sites and infrastructure using a mobile emulator that monitors requests triggered on a browser. We support iPhone4s and Android, and have the ability to playback a mobile HAR file.</p>
<p><span style="color: #000000;">By the time we are writing this we are already 2 weeks from the March release with more cool new things coming!</span></p>
<p><strong>The Catchpoint Team.</strong></p>

With more and more people relying solely on mobile and tablet devices to browse the web and perform basic tasks, the role of the PC is losing its place as a household staple. <a href="http://news.cnet.com/8301-10805_3-57392789-75/former-microsoft-exec-ozzie-of-course-were-in-a-post-pc-world/" target="_blank">Even former Microsoft Executive Ray Ozzie, chief software architect, claims we are in a “Post-PC” Era</a>. However, there are still tasks associated with high bandwidth, availability, computing that require the PC. At the end of the day, we are moving in to a “PC plus” world rather than “Post PC”.</p>
<p><strong>Cloud Computing Saboteurs and Counter Intelligence</strong><br />
Everyone is leasing datacenter space these days, including major internet giants like Google. Fear of neighboring competition sneaking a peak at top secret hardware caused Google <a title="Google Datacenter Security" href="http://www.wired.com/wiredenterprise/2012/03/google-miner-helmet/" target="_blank">to turn off the lights and close the blinds in their part of the corridor</a>. Only Google employees can ascend into the darkness, equipped with a head lamp of course.  We wonder though, if a competitor made past security and into the Google datacenter &#8211; what would stop them from bringing a flashlight?</p>
<p>This fear is not without reason however, as everyone is trying to build <a href="http://www.datacenterknowledge.com/archives/2012/03/14/estimate-amazon-cloud-backed-by-450000-servers/" target="_blank">a better, bigger, and more efficient cloud computing solution.</a> A recent study released by Huan Liu at Accenture Technology Labs, predicted that Amazon’s Web Services is powered by at least 454,400 servers across seven global data center hubs.</p>

Google is not only saving electricity by cutting the lights – they are also taking a creative approach to going green <a href="http://gigaom.com/cleantech/flush-a-toilet-and-cool-googles-data-center/" target="_blank">by spraying recycled waste water on servers</a> to keep a new datacenter cool.</p>
<p><strong>Stormy Days</strong><br />
<a href="http://blog.scalyr.com/2012/03/13/the-azure-outage-time-is-a-spof-leap-day-doubly-so/" target="_blank">Leap Day 2012 was the trip and stumble felt around the world for Microsoft Azure</a>.  A calendar bug caused failures in Azure clusters all over the world when all regions entered Leap Day at the same moment (proving redundancy is not perfect). Combined with the <a href="http://www.thewhir.com/web-hosting-news/amazon-ec2-users-critical-of-delayed-status-updates-during-brief-cloud-outage" target="_blank">recent Amazon EC2 hiccups</a>, companies are now re-considering their cloud strategies and looking at a <a href="http://gigaom.com/cloud/outages-prompt-multi-cloud-evaluations/" target="_blank">multi-vendor approach</a>.</p>

The Chromium team ran several performance tests for DNS resolution on IPv6 enabled machines and it was not happy with the resolution speed of the OS (Windows, Mac, or Linux).  As a result the team is working on building their own DNS stub resolver to distribute with Chrome browser.</p>
<p><strong><a href="http://www.blaze.io/technical/your-laptop-screen-just-got-smaller/" target="_blank">Higher Resolution, Smaller Screens, More Performance Headaches</a></strong><br />
The release of the new iPad, boasting an even-more-retinal-display, is causing a surge in the population of people surfing the web with HD screens. This will have huge impact on how images are served as normal resolution images appear fuzzy on HD screens. The solution isn’t as clear-cut as just increasing resolution &#8211; images account for about 60% of total downloaded bytes and tripling the resolution to keep up with iPads will cause the page size to double!</p>

Microsoft engineers not only rethought the desktop experience in building Windows 8, but they also did a complete makeover in IE, optimizing the browsing experience for keyboard, mouse, and touch. Look for a completely new way to integrate websites and apps as designers sought to make heavy workflow as seamless as possible.</p>

<p><strong>Cloud Pricing Wars – Game On</strong><br />
Last week,  <a title="Amazon Leads Price War: Drops AWS Pricing Again, Leans Heavy on Reserved Instances" href="http://www.readwriteweb.com/cloud/2012/03/amazon-leads-price-war-drops-a.php" target="_blank">Amazon AWS reduced their prices</a> by as much as 42% for certain reserved EC2 instances. This was the 19th time Amazon lowered their prices and it triggered a pricing war in the cloud space. <a title="Google to Amazon: You’re not the only price chopper around" href="http://gigaom.com/cloud/google-to-amazon-youre-not-the-only-price-chopper-around/" target="_blank">Google was quick to announce</a> on the same day their new reduced prices that are slightly lower than AWS. While 3 days later <a title="Announcing Reduced Pricing on Windows Azure Storage and Compute" href="http://blogs.msdn.com/b/windowsazure/archive/2012/03/08/announcing-reduced-pricing-on-windows-azure-storage-and-compute.aspx" target="_blank">Microsoft followed up with prices cuts on Azure</a>.  While the lower prices will help with the migration to the cloud, companies shopping for a cloud provider are still challenged by the difference in the computing instances packages which make any comparison quite hard. Maybe the Cloud Providers need to introduce a price/unit concept like the products in your local grocery shelves.<br />
<strong><a title=" As web booms, so does demand for data centers" href="http://gigaom.com/cloud/as-web-booms-so-does-demand-for-data-centers/" target="_blank">Web boom causes demand for new data centers</a></strong><br />
A new report out by Campos Research and Analysis on behalf of Digital Realty Trust shows a growing demand for more data centers worldwide. In North America 92% of the respondents claimed they will probably to definitely increase their <em>colo spending</em> this year in the US, Europe, Asia Pacific, and South America, in order of planned expansion.  85% of respondents worldwide intend to increase resources as opposed to 82% at the end of 2010.<br />
<a title="Bonobos Used This Creative 'Error' Page To Prevent An Online PR Disaster  Read more: http://www.businessinsider.com/bonobos-used-this-creative-error-page-to-prevent-an-online-pr-disaster-2012-3#ixzz1owRpkK1g" href="http://www.businessinsider.com/bonobos-used-this-creative-error-page-to-prevent-an-online-pr-disaster-2012-3" target="_blank"><strong>Creative Crash Pages Making the Best Out of a Bad Situation</strong> </a><br />
Despite ample prevention, all sites are bound to crash or be unavailable at some point. How a company handles such scenario, can make a difference.  Bonobos showed during the Small Business Summit 2012 that with a little bit of humor and a dash of humility, a well thought out Down Page can turn a revenue crisis into a marketing opportunity, even if the crash happened on Cyber Monday.  Other retailers should take notice and plan for similar action in 2012 &#8211; it pays off to be ready.<br />
<a title="IBM’s Holey Optochip Pumps 1 Trillion Bits per Second" href="http://www.wired.com/wiredenterprise/2012/03/ibm-networking/" target="_blank"><strong>IBM Processor Can Move Data at 1 Tb/s</strong> </a><br />
As computing technology is advancing and servers pack more and more processors, the network overhead or latency is becoming a growing bottleneck. IBM released a new solution, the Holey Optochip, which can move data at 1 trillion bits per second (1 terabyte per second) by firing lasers through the 48 holes in the chip. The Holey Octochip (not for sale) is 8 times faster than the fastest chips in the market today and 10k times faster than a standard 100 Mb/s Ethernet connection.</p>
