<p>More <a href="https://www.nytimes.com/2020/07/17/technology/twitter-hackers-interview.html">details</a> have emerged about the Twitter break-in last week, leading some to utter the quote above. Here&#8217;s a take on how to see it as not being about &#8220;stupidity&#8221;.</p>

<p>The data in your database <em>should</em> be consistent&#8230; but then again, incidents <em>shouldn&#8217;t</em> happen, right? Slack accepts that things routinely go wrong with data at their scale, and they have framework and a set of tools to deal with it.</p>

<p>I learned a lot from this article. My favorite obstacle is &#8220;distancing through differencing&#8221;, e.g. &#8220;we would never have responded to an incident that way&#8221;.</p>

<p>This podcast episode was kind of like a preview of J. Paul Reed and Tim Heckman&#8217;s joint talk at <a href="SRE From Home">https://srefromhome.com/</a>. I love how they refer to the pandemic as a months-long incident, and point out that if you&#8217;re always in an incident then you&#8217;re never in an incident.</p>
