This works when traffic is predictable. It falls apart when it&rsquo;s not.</p> <p>At 10,000 requests per second, 10 failures is noise &ndash; a 0.1% error rate. A static threshold trips the circuit on what&rsquo;s essentially a healthy service. At 10 requests per second, 10 failures is total collapse &ndash; 100% error rate over one interval. The same threshold that false-positives under high traffic is too slow to protect under low traffic.</p>
