<div class="sreweekly-description">
<p>Opzzz is a new app that graphs sleep data (from a Fitbit) against pager alerts (from PagerDuty or Server Density). I love this idea!</p>
<blockquote><p>By correlating sleep data with on call incidents, we can then illustrate the human cost of on-call work.</p></blockquote>

<div class="sreweekly-description">
<p>Speaking of measuring sleep data against pages, Etsy is doing that too with their open source on-call analysis tool Opsweekly. Engineers also classify their events based on whether they were actionable.</p>
<blockquote><p>We’ve been doing this for a year and we are seeing an increasingly improving signal to noise ratio.</p></blockquote>

<div class="sreweekly-description">
<p>I&#8217;m a firm believer in work/life balance, especially as it pertains to on-call. I have a reputation for rigidly defending my personal time and that of my co-workers. I strongly feel that this is the best thing I can do for my company because exhaustion and burnout are huge reliability risks. Read this article if you&#8217;re trying to figure out how to improve your on-call experience and aren&#8217;t sure how to start.</p>

<div class="sreweekly-description">
<p>A really detailed article about how one company got Docker into production safely and reliably. I especially love the parts about nginx cutover (when deploying new container versions) and supervising running containers. With the common refrain that <a href="http://techbeacon.com/containers-reality-check-why-theyre-still-not-production-ready">Docker isn&#8217;t ready for production</a>, it&#8217;s nice to see how GoCardless did it &#8212; but it&#8217;s also interesting to see how much tooling they felt compelled to write in-house.</p>

<div class="sreweekly-description">
<p>What good is an arbitrary number of nines from a cloud service provider if their transit links go down? Or if vast swathes of end-users can&#8217;t reach your site due to a major internet disruption? ServiceNow&#8217;s vice president argues that cloud providers must pay attention to &#8220;real availability&#8221; and partner with their customers to deal with external threats to availability.</p>

<div class="sreweekly-description">
<p>Last month, Bitfinex (a bitcoin exchange) experienced multiple outages, and the subsequent bitcoin sell-off caused the price of the bitcoin to drop 7.5%. Bitcoin&#8217;s lack of regulation is a blessing, but is it also a curse?</p>

<p>How can I even intro a gem like this? John Allspaw&#8217;s essay on blameless and just culture at Etsy is a classic, and it&#8217;s a great read even if you&#8217;re well-versed in the topic. I especially liked the concept of the &#8220;Second Story&#8221;.</p>
