<p>Lots of outages this week, although not as many as in some previous years on Black Friday.  We&#8217;ll see what Cyber Monday brings.</p>
<p>I&#8217;m writing this from the airport on my way to re:Invent.  Perhaps I&#8217;ll see some of you there as I rush about from meeting to meeting.</p>

<div class="sreweekly-description">
<p>As the title suggests, this article by New Relic is about the mindset of an SRE. I really love number 3, where they discuss the idea that gating production deploys can actually reduce reliability rather than improve it.</p>

<div class="sreweekly-description">
<p>It&#8217;s what it says on the tin, and it&#8217;s targeted for DigitalOcean. One could also use this as a general primer on setting up HeartBeat failover using other cloud platforms.</p>

<div class="sreweekly-description">
<p>The three pitfalls discussed are confusing EBS latency, idle EC2 instances wasting money, and memory leaks. My favorite gotcha isn&#8217;t mentioned: performance cliffs caused by running out of burst in T2 instances or GP2 volumes.</p>
