Question

A major incident triggers dozens of alerts firing at once across many services. As the responder, how do you avoid being overwhelmed and find the real problem?

Stop the bleeding first (mitigate), then form hypotheses from real signals. Separate root cause from symptom, communicate status as you go, and close with what prevents a repeat.
