<p>Last week, I linked to a reddit story of an engineer that was unfairly fired for a mistake on their first day. Dr. Richard Cook picked this up and wrote up a great analysis of the underlying organizational issues.</p>

<div class="sreweekly-description">
<p>This was released the week before last, but it took me awhile to digest it. The ATO did a very thorough post-analysis on their two outages and released this polished report. I like that they took full responsibility for the outage even though it was an issue with a fully-managed vendor SAN offering, and they clearly sought to learn as much as possible.</p>

<div class="sreweekly-description">
<p>Frustrated by British Airways&#8217;s Willie Walsh&#8217;s public statement regarding their major outage, TripWire founder Gene Kim took it upon himself to write an open letter of apology as if he were an airline CEO.  It&#8217;s pretty great.</p>

<p>I&#8217;ve been following GitLab&#8217;s blog since their engineer accidentally deleted their database earlier this year, and I&#8217;m glad I did. This article touches on all sorts of topics near to my heart: preventing burnout, examining incident response metrics, enforcing vacations, incident command, and having developers go on-call for what they wrote.</p>
