Incident Response Checklist
Detect, triage, mitigate, resolve, postmortem — the steps that hold under pressure.
Checklist steps
- Declare incident
Open the incident channel. Assign IC, Comms, Scribe.
- Triage severity
Sev1: outage or data loss. Sev2: major degradation. Sev3: partial impact. Sev4: low impact.
- Update status page
Within 5 minutes for Sev1/Sev2. Be honest, no jargon.
- Mitigate
Stop the bleeding first. Root cause can wait.
- Resolve
Confirm restoration with metrics and synthetic checks.
- Postmortem
Blameless. Timeline, root cause, action items with owners.
Frequently asked questions
Who declares an incident?
Anyone can. Better to over-declare than under-declare.
