Runbook: Incident Response
Severity matrix
| Severity | Definition | Response |
|---|---|---|
| Critical | Authentication, data integrity or full API outage | Immediate mitigation, status update, postmortem |
| Major | Major feature unavailable or degraded for many users | Triage, workaround, status update |
| Minor | Limited feature impact | Track, fix, communicate if user-visible |
Procedure
- Confirm the symptom using
/api/health,/api/status, logs and DB metrics. - Assign an incident owner.
- Freeze risky deployments if the issue is production-wide.
- Publish status if users are affected.
- Mitigate: rollback, disable feature, rotate secret, scale dependency or patch data.
- Capture timeline and evidence.
- Close with a postmortem and preventive actions.
