<h2 style="text-align: center; font-size: 80%; color: #909090;">A message from our sponsor, <a href="https://sreweekly.com/link/513">incident.io</a>:</h2>
<p>“Lifting and shifting” noise to new tools just buys a different UI for the same burnout. <a href="https://sreweekly.com/link/513">incident.io&#8217;s migration framework</a> prioritizes service cataloging and inventory to fix ownership, preventing team friction during the transition to a scalable on-call system.</p>

<div class="sreweekly-description">
<p>A previously unpublished article by the late Dr. Richard Cook!</p>
<blockquote>
<p>Organizational Second Hit Syndrome is an incident-related phenomenon analogous to neurological second-impact-syndrome (SIS). It occurs when a major incident creates a vulnerable period during which a second incident generates strong, widespread, and sometimes destructive organizational reactions.</p>

<p>Autoscaling is reactive, not resilient. Without caps, metrics, or overrides, it can worsen failures. True elasticity requires policy, testing, and bottleneck awareness.</p>
