Production Incident Management Questions

Production/service incident response: how an on-call engineer detects, triages, and resolves outages or reliability degradation. Covers detection via monitoring metrics, logs, and distributed traces; mitigation via rollbacks, circuit breakers, feature flags, or network ACLs; incident communication and stakeholder updates; root-cause analysis; and blameless postmortems. No adversary, no malware, no legal evidence chain: the concern is system failure and reliability, not intrusion or malicious activity.
