<p>I&#8217;m back! The death plague was pretty terrible. <a href="https://xkcd.com/325/">A&#8211;</a>, would not buy from again. I&#8217;m still catching up on articles from the past couple of weeks, so if I missed something important, please send a link my way!</p>
<p>I&#8217;m going to start paring down the Outages section a bit. In the past year, I&#8217;ve learned that telecom providers have outages all the time, and people complain loudly about them. They also generally don&#8217;t share useful postmortems that we can learn from. If I see a big one, I may still report it here, but for the rest, I&#8217;m going to omit them.</p>

<div class="sreweekly-description">
<p>Gabe Abinante has been featured here previously for his contributions to the <a href="https://github.com/Operations-Incident-Board/Postmortem-Report-Reviews">Operations Incident Board: Postmortem Report Reviews</a> project. To kick off this year&#8217;s sysadvent, here&#8217;s his excellent argument for having a defined postmortem process.</p>

<div class="sreweekly-description">
<p>Having a change management process is useful, even if it&#8217;s just a deploy/rollback plan. I knew all that, but this article had a really great idea that I hadn&#8217;t thought of before (but should have): your rollback plan should have a set of steps to <i>verify that the rollback was successful</i>.</p>

<div class="sreweekly-description">
<p>Let&#8217;s be honest: being on-call is kind of an ego boost. It makes me feel important. But <i>not</i> getting paged is way better than getting paged, and we should remember that. <a href="https://twitter.com/hashtag/oncallselfie">#oncallselfie</a></p>

<div class="sreweekly-description">
<p>It&#8217;s that time of year again! In a long-standing (1-year-long) tradition here at SRE Weekly, I present you this year&#8217;s State of On-Call report from my kind sponsor, VictorOps.</p>

<div class="sreweekly-description">
<p>Storing 99th and 95th percentile latency in your time-series DB is great, but what if you need a different percentile? Or if you need to see <i>why</i> those 1% of requests are taking forever? Perhaps they&#8217;re all to the same resource?</p>

<div class="sreweekly-description">
<p>Orchestrator is a tool for managing a (possibly complex) tree of replicating MySQL servers. This includes master failure detection and automatic failover, akin to <a href="https://code.google.com/p/mysql-master-ha/">MHA4Mysql</a> and other tools. GitHub has adopted Orchestrator and shares some details on how they use it.</p>

<p>A few notable brands suffered impaired availability on and around Black Friday this year. Hats off to AppDynamics for giving us some hard numbers.</p>

<div class="sreweekly-description">
<p>Looks like I missed this &#8220;Zero Outage Framework&#8221; announcement the first time around. I love the idea of information-sharing and it&#8217;ll be interesting to see what they come up with. We can all benefit from this, especially if the giants like Microsoft join up.</p>

<div class="sreweekly-description">
<p>All IT managers would do well to heed this advice. Remember, burnout very often directly and indirectly impacts reliability.</p>
<blockquote><p>&#8220;If you’re a manager and you are replying to email in the evening, you are setting the expectation to your team – whether you like it or not – that this is normal and expected behaviour&#8221;</p></blockquote>

<p>Signifai has this nice write-up about setting up redundant DNS providers. My favorite bit is how they polled major domains to see who had added a redundant provider since October 21, and they even shared the source for their polling tool!</p>

<p>I&#8217;ve featured a lot of articles lately about reducing the amount of code you write. But does that mean that it&#8217;s always better to contract with a SaaS provider? This week&#8217;s <i>Production Ready</i> delves into the tradeoffs.</p>
