<p>Check out this new 100-page ebook on incident response from Atlassian, great for folks setting up a brand new on-call structure or improving their existing one. It even has a section on compensating teams for being on-call.</p>

<p>In this case, the &#8220;cloud&#8221; refers to actual clouds, the ones in the sky. It&#8217;s a comparison between concepts in aviation and SRE, fields that have significant overlaps.</p>

<div class="sreweekly-description">
<blockquote><p>[&#8230;] I’m no longer going to try do get engineers to stop saying root cause <em>while they are engaged in an incident</em>. If the experts at anomaly response find it a useful phrase while they are doing their work, we should recognize this as a part of their expertise.</p></blockquote>

<blockquote><p>Slack&#8217;s server infrastructure scales up every day to handle volume in North America by increasing the size of the server pool available to handle requests. Some of these servers did not successfully register with our load balancing infrastructure during this process of scaling up, and this ultimately led to a decline in the health of the server pool over time.</p></blockquote>
