Service Recovery Flow

1. Identify failing resource and root dependency
2. Capture logs and events before restart
3. Apply minimal corrective change
4. Restart only affected workload
5. Re-validate user-facing flow

Recovery Guidelines

• Fix root cause before restarting repeatedly
• Avoid force changes without backup
• Record incident timeline for postmortem
