<div class="sreweekly-description"><p>If you&#8217;ve ever been in an incident where communication suddenly went quiet and access got restricted, this article explains why. The author breaks down five fundamental ways security incident response diverges from outage response — and why the instincts that make you effective at one can actively work against you in the other.</p>

<p>[&#8230;] in practice, microservices that share a database or coordinate on every request are a distributed monolith with extra latency and a much harder debugging story.</p>
