<div class="sreweekly-title"><a href="https://increment.com/on-call/" target="_blank">Increment: On-Call</a></div>
<div class="sreweekly-description">
<p>The big story this week is the release of the inaugural issue of <i>Increment</i>, a newsletter by Stripe, edited by Susan Fowler. They bill it as &#8220;A digital magazine about how teams build and operate software systems at scale&#8221; and the first issue, dedicated to on-call, certainly delivers. Below, I&#8217;ll include my short take on each article in the issue.</p>
</div>
</div>
<div class="sreweekly-entry">
<div class="sreweekly-title"><a href="https://increment.com/on-call/when-the-pager-goes-off/" target="_blank">What happens when the pager goes off?</a></div>
<div class="sreweekly-description">
<p><i>Increment</i> interviewed over thirty companies to build a picture of the common practices in incident response. I&#8217;m actually pretty surprised to hear that &#8220;it turns out that they all follow similar (if not completely identical) incident response processes&#8221;, but apparently the commonalities don&#8217;t stop at just process:</p>
<blockquote><p>Slack and PagerDuty appear to be two points of failure across the entire tech industry</p></blockquote>
<p>Bonus content: Julia Evans shared her <a href="https://twitter.com/b0rk/status/852589061810376705">notes</a> on Twitter.</p>

<div class="sreweekly-title"><a href="https://increment.com/on-call/who-owns-on-call/" target="_blank">Who owns on-call?</a></div>
<div class="sreweekly-description">
<p>Next up, <em>Increment</em> addresses the dichotomy of ops teams versus developers on call for their code. It turns out that the latter practice is more prevalent than I&#8217;d realized.</p>
</div>
</div>
<div class="sreweekly-entry">
<div class="sreweekly-title"><a href="https://increment.com/on-call/crafting-sustainable-on-call-rotations/" target="_blank">Crafting sustainable on-call rotations</a></div>
<div class="sreweekly-description">
<p>After laying a solid groundwork of suggestions for avoiding burn-out in on-call, this next <em>Increment</em> article raises a really important point: <b>on-call affects people differently based on privilege</b>. Example: single parents are going to have a much harder time of it.</p>
<blockquote><p>[&#8230;] if you set up an on-call rotation with a schedule or intensity that assumes the participants have no real responsibilities outside of the office, you are limiting the people who will be able to participate on your team.</p></blockquote>

<div class="sreweekly-title"><a href="https://increment.com/on-call/the-benefits-of-transparency/" target="_blank">The benefits of transparency</a></div>
<div class="sreweekly-description">
<p>Remember a couple of months back when GitLab live-streamed their incident response? <i>Increment</i> caught up with their CEO to give us this in-depth interview about their radical transparency.</p>
</div>
</div>
<div class="sreweekly-entry">
<div class="sreweekly-title"><a href="https://increment.com/on-call/on-call-at-any-size/" target="_blank">On-call at any size</a></div>
<div class="sreweekly-description">
<p><em>Increment</em> shares tips and key practices for setting up on-call, targeted to companies of size ranges varying from 0-10 employees all the way up to 10000+.</p>

<p><i>Increment</i> rounds out their issue with advice in the form of quotes from six of the companies they interviewed.</p>

<div class="sreweekly-description">
<p>The other big news of the week is the official <a href="https://honeycomb.io/blog/2017/04/honeycomb-launch/">launch</a> of Honeycomb.io. If you haven&#8217;t had a chance to check it out yet, here&#8217;s an introduction, and you can also sign up for a <a href="https://ui.honeycomb.io/signup">free one-month trial</a>.</p>

<ul class="sreweekly-outage">
<li class="sreweekly-outage">A DDoS took out their DNS service, taking out customer domains and also sites they they host for customers. While this is a news article and not a formal post-analysis, it does include some pretty interesting technical detail from an interview with their CTO. I&#8217;m not sure that he did himself any favors by quoting the definition of their SLA:<br />
<blockquote><p>&#8220;People look at 99.9 per cent and think that&#8217;s seconds of downtime, but you work it out and it&#8217;s 45 minutes.&#8221;</p></blockquote>

<ul class="sreweekly-outage">
<li class="sreweekly-outage">Google Cloud LB threw 502s for 25% of requests in a 22-minute period. They released this post-analysis 7 days later, and I have to say, the root cause is pretty interesting – and sadly familiar.<br />
<blockquote><p>A bug in the HTTP(S) Load Balancer configuration update process caused it to revert to a configuration that was substantially out of date.</p></blockquote>
