<div class="sreweekly-title"><a href="https://blog.serverdensity.com/humanops/" target="_blank">HumanOps</a></div>
<div class="sreweekly-description">How did I not know about HumanOps before now?? Their <a href="http://humanops.com">site</a> is great, as is their <a href="https://github.com/HumanOps/HumanOps/blob/master/HumanOps.rst">manifesto</a>. A large part of what I do at $JOB is to study and improve the human aspects of operations.</p>
<blockquote><p>The wellbeing of human operators impacts the reliability of systems.</p></blockquote>

<div class="sreweekly-title"><a href="https://blog.serverdensity.com/how-we-handle-on-call-schedules/" target="_blank">DevOps On-Call: How we Handle our Schedules</a></div>
<div class="sreweekly-description">Here&#8217;s a description of how Server Density handles their on-call duties. They use a hybrid approach with some alerts going to devs and some handled by a dedicated ops team. This idea is really intriguing to me:</p>
<blockquote><p>After an out-of-hours alert the responder gets the following 24 hours off from on-call. This helps with the social/health implications of being woken up multiple nights in a row.</p></blockquote>

<div class="sreweekly-title"><a href="http://techblog.netflix.com/2016/07/product-integration-testing-at-speed-of-Netflix.html" target="_blank">Product Integration Testing at the Speed of Netflix</a></div>
<div class="sreweekly-description">This article is written by Netflix&#8217;s integration testing team, which is obviously not their SRE team. Nevertheless, integration testing at Netflix is important to ensure that new features start out working reliably and stay working after they&#8217;re out.</div>

<div class="sreweekly-description">The pitfall discussed in this article is a lack of packet-level visibility that hampers operators&#8217; ability to quickly diagnose network issues. The article starts by outlining the issue then discusses methods of mitigating it including Tap As a Service.</div>

<div class="sreweekly-description">This article makes the case for out of band management (OOBM) tools in responding to network issues. It&#8217;s good review, especially for those that have experience primarily or solely with cloud infrastructure.</div>

<div class="sreweekly-description">Now there&#8217;s an inflammatory article title &#8212; it reeks of the NoOps debate. I would argue that a microservice architecture makes an RCA just as necessary if not more so.</div>

<div class="sreweekly-title"><a href="https://www.linux.com/news/how-devops-failed-60k-users" target="_blank">How DevOps Failed 60K Users</a></div>
<div class="sreweekly-description">Former Slideshare engineer Sylvain Kalache shares this war-story about DevOps gone awry. I&#8217;d say there&#8217;s a third takeaway not listed in the article: DevOps need not mean full access to the entire infrastructure for everyone.</div>

<p>NPM had an 8+ hour outage that left many build system providers such as <a href="https://twitter.com/traviscistatus/status/750618512977125376?lang=en">Travis</a>, CircleCI, and <a href="https://status.heroku.com/incidents/918">Heroku</a> and individual users scrambling. Their <a href="http://blog.npmjs.org/post/147012483540/package-tarball-read-outage-today">postmortem</a> indicates that a major end-of-day deploy the day before was to blame. Conversation in a related <a href="https://github.com/npm/npm/issues/13284">github issue</a> suggests a monitoring gap and a lack of overnight on-call coverage for complex outages such as this one.</p>
