A production outage, a terminal, and a running clock. This is how we work: read the evidence, reject the reflexes, trace the symptom to its root, and fix the cause. Now you try.
Real logs stream in. The clock runs. Every rollback and every guess costs customer impact. Find the root cause and fix it before impact hits 100.

p99 latency on checkout-api jumped from 180ms to 7.4s. Checkout conversion is dropping. You are the on-call engineer. Find the root cause and fix it.
Support reports customers charged twice in the last 6 hours. No failed requests. No errors on any dashboard. Every dashboard is green. Find what is double-charging them and stop it.
Your rank is based on time to resolution, and customer impact rises every second the incident is open. Rollbacks and blind scaling cost you time without touching the cause. The fastest path runs through evidence: status, metrics, logs, config, then a targeted fix.
