A single routing or firewall edit can quietly break an application dependency, pull reachability from a whole region, or take the business offline for hours.</p> <p>The usual response (freezes, heavier approval boards, rarer maintenance windows) feels like risk reduction but isn&rsquo;t. Research from MIT Sloan&rsquo;s System Dynamics group shows it does the opposite. Each control added after a failure quietly raises the odds of the next one, and the organization spends years tightening the loop on itself.</p>
