<p>This is a video recording of a talk by Charity Majors at Monkigras 2018. She has a lot of awesome stuff to say about making on-call enjoyable and owning your code, including this gem:</p>
<blockquote><p>Babies, by the way, are engineered by evolution to be too cute for you to want to kill them. Your code is not.</p></blockquote>

<p>To shamelessly steal a line from this recorded talk, it&#8217;s very rarely the right thing for your observability system&#8217;s scale to match that of the system it&#8217;s observing. To avoid that, you need to throw away some event data rather than storing and indexing everything. How do you do that while still achieving functioning observability?</p>

<p>Actually, I&#8217;ve linked to their generic &#8220;status history&#8221; page, since that seems to be as specific as I can get. <strong>Readers from Microsoft</strong>, perhaps you could ask the folks that run the Azure status page to create dedicated permalinks for each incident, or at least for each RCA? Even an anchor link in the status history page would be super-awesome!</li>
