<div class="sreweekly-description">
<p>Here&#8217;s another great article urging caution when adopting new tools. Codeship&#8217;s Jessica Kerr categorizes technologies into a continuum of risk, from single-developer tools all the way up to new databases. She goes into a really excellent amount of detail, providing examples of how adopting a new technology can come back to bite you.</p>

<p>After several recent incidents of nations cutting off or severely curtailing internet connectivity, the UN took a stand, as reported in this Register article: </p>
<blockquote><p>The United Nations officially condemned the practice of countries shutting down access to the internet at a meeting of the Human Rights Council on Friday.</p></blockquote>

<div class="sreweekly-description">
<p>Mathais Lafeldt is back in this latest issue of Production Ready. In this part 1 of 2, he reviews Richard Cook&#8217;s classic <i>How Complex Systems Fail</i>, with an eye toward applying it to web systems.</p>

<div class="sreweekly-description">
<p>And with a nod to Lafeldt for the link, here&#8217;s another classic from John Allspaw on complexity of failures.</p>
<blockquote><p>In the same way that you shouldn’t ever have root cause &#8220;human error&#8221;, if you only have a single root cause, you haven’t dug deep enough.</p></blockquote>

<div class="sreweekly-description">
<p>SGX released a postmortem for their mid-July outage in the form of a press release. Just as Allspaw tells us, the theoretically simple root cause (disk failure) was exacerbated by a set of complicating factors.</p>
