<p>Sorry I&#8217;m a tad late this week!</p>
<p>If you only have time to read one long article, I highly recommend this first one.</p>

<div class="sreweekly-title"><a href="https://backchannel.com/how-technology-led-a-hospital-to-give-a-patient-38-times-his-dosage-ded7b3688558#.l2mo3zokn" target="_blank">How Technology Led a Hospital To Give a Patient 38 Times His Dosage</a></div>
<div class="sreweekly-description">This fascinating series delves deeply into the cascade of failures leading up to the nearly fatal overdose of a pediatric patient hospitalized for a routine colonoscopy. It&#8217;s a five-article series, and it&#8217;s well worth every minute you&#8217;ll spend reading it. Human error, interface design, misplaced trust in automation, learning from aviation; it&#8217;s all here in abundance and depth.</div>

<div class="sreweekly-description">In this second part of a two part series (featured here last week), Charity Majors delves into what operations means as we move toward a &#8220;serverless&#8221; infrastructure.</p>
<blockquote><p>If you chose a provider, you do not get to just point your finger at them in the post mortem and say it’s their fault.  <b>You chose them, it’s on you.</b></p></blockquote>

<div class="sreweekly-description">Interesting, though I have to say I&#8217;m a bit skeptical when I hear someone target six nines. Especially when they say this:</p>
<blockquote><p>Redefining five nines is redefining them to go up to six nines,&#8221; said James Feger, CenturyLink&#8217;s vice president of network strategy and development [&#8230;]</p></blockquote>

<p>A major outage in one availability zone took down many sites and services in Australia. Amazon quickly released this detailed post-analysis. TL;DR: an extended utility voltage sag didn&#8217;t cause isolation breakers to trip, and the flywheel UPSes then quickly dumped all of their energy into the power grid.</p>
