<p>Salt is Cloudflare&#8217;s configuration management tool.</p>
<blockquote>
<p>How do you find the root cause of a configuration management failure when you have a peak of hundreds of changes in 15 minutes on thousands of servers?</p>
<p>The result of this has been a reduction in the duration of software release delays, and an overall reduction in toilsome, repetitive triage for SRE.</p>

<p>In this post, I’ll give a high-level overview of what Temporal offers users, the problems we were experiencing operating Spinnaker that motivated its initial adoption at Netflix, and how Temporal helped us reduce the number of transient deployment failures at Netflix from 4% to 0.0001%.</p>

<p>In 2019, Charity Majors came down hard on deploy freezes with an article, <a href="https://substack.com/home/post/p-181561576">Friday Deploy Freezes are Exactly Like Murdering Puppies</a>. </p>
<p>This one takes a more moderate approach: maybe a deploy freeze is the right choice for your organization, but you should work to understand why rather than assuming.</p>
