Incident Response Process
- Detection: Alerts fire → on-call engineer acknowledges within 5 minutes. Or customer reports via support → escalated to on-call
- Triage: Assess severity and impact — how many users affected? Is it getting worse? Does it warrant a full incident response or just a quick fix?
- Incident Commander: Assign an IC who coordinates the response — they don't fix things, they manage communication, delegate tasks, and make decisions
- Communication: Send regular updates (every 15-30 min for P0) to stakeholders via status page, Slack, email. Transparency builds trust even during outages
- Mitigation: Focus on stopping the bleeding FIRST — rollback, feature flag, restart, failover. Root cause investigation comes after the fire is out
- Resolution: Confirm the issue is fully resolved, verify monitoring shows recovery, update status page, and schedule a postmortem
Blameless Postmortems
- Core Principle: Focus on systemic factors, not individual blame — 'The deployment system allowed untested code to reach production' not 'John deployed bad code'
- Timeline: Detailed chronological record — when was the issue detected, who responded, what actions were taken, when was it resolved
- Root Cause Analysis: Use the '5 Whys' method — keep asking why until you reach systemic causes (process, tooling, automation gaps)
- Action Items: Concrete, assigned, time-bound improvements — 'Add integration tests for payment flow (Assigned: Team A, Due: March 15)'
- Sharing: Publish postmortems internally (or externally like Cloudflare and GitLab do) — organizational learning prevents repeat incidents
- Follow-up: Track action item completion — unfollowed postmortem action items are worse than no postmortem because they create false confidence
