<p>What can the fire service learn about safety from the aviation industry? A 29-year veteran in the fire service answers that question in detail. We could in turn apply all of those lessons to operating complex infrastructures.</p>

<p>I&#8217;m surprised that I haven&#8217;t come across the term &#8220;High Reliability Organization&#8221; before reading the previous article. Here&#8217;s Wikipedia&#8217;s article on HROs.</p>
<blockquote><p>A high reliability organization (HRO) is an organization that has succeeded in avoiding catastrophes in an environment where normal accidents can be expected due to risk factors and complexity.</p></blockquote>

<div class="sreweekly-description">
<p>I wrote this article on my terrible little blog back in 2008 &#8212; forgive the horrid theme and apparently broken unicode support. This was well before I worked in Linden Lab&#8217;s Ops team, back when I was making a living as a user selling content in Second Life. What&#8217;s interesting to me in reading this article 8 years later is the user perspective on the impact of the string of bad outages, and especially Linden&#8217;s poor communication during outages.</p>
