Severity Classification Matrix

# Incident Severity Framework

| Level | Name      | Criteria                                           | Response Time | Update Cadence | Escalation              |
|-------|-----------|----------------------------------------------------|---------------|----------------|-------------------------|
| SEV1  | Critical  | Full service outage, data loss risk, security breach | < 5 min       | Every 15 min   | VP Eng + CTO immediately |
| SEV2  | Major     | Degraded service for >25% users, key feature down   | < 15 min      | Every 30 min   | Eng Manager within 15 min|
| SEV3  | Moderate  | Minor feature broken, workaround available           | < 1 hour      | Every 2 hours  | Team lead next standup   |
| SEV4  | Low       | Cosmetic issue, no user impact, tech debt trigger    | Next bus. day  | Daily          | Backlog triage           |

## Escalation Triggers (auto-upgrade severity)
- Impact scope doubles → upgrade one level
- No root cause identified after 30 min (SEV1) or 2 hours (SEV2) → escalate to next tier
- Customer-reported incidents affecting paying accounts → minimum SEV2
- Any data integrity concern → immediate SEV1

Incident Response Runbook Template

B1bash

Identify the last known good revision

kubectl rollout history deployment/<service> -n production

Rollback to previous version

kubectl rollout undo deployment/<service> -n production

Verify rollback succeeded

kubectl rollout status deployment/<service> -n production

watch kubectl get pods -n production -l app=<service>

B2bash

Rolling restart — maintains availability

kubectl rollout restart deployment/<service> -n production

Monitor restart progress

kubectl rollout status deployment/<service> -n production

B3bash

Increase replicas to handle load

kubectl scale deployment/<service> -n production --replicas=<target>

Enable HPA if not active

kubectl autoscale deployment/<service> -n production \

--min=3 --max=20 --cpu-percent=70

## Root Cause Analysis
### What happened
[Detailed technical explanation of the failure chain]

### Contributing Factors
1. **Immediate cause**: [The direct trigger]
2. **Underlying cause**: [Why the trigger was possible]
3. **Systemic cause**: [What organizational/process gap allowed it]

### 5 Whys
1. Why did the service go down? → [answer]
2. Why did [answer 1] happen? → [answer]
3. Why did [answer 2] happen? → [answer]
4. Why did [answer 3] happen? → [answer]
5. Why did [answer 4] happen? → [root systemic issue]

## What Went Well
- [Things that worked during the response]
- [Processes or tools that helped]

## What Went Poorly
- [Things that slowed down detection or resolution]
- [Gaps that were exposed]

## Action Items
| ID | Action                                     | Owner       | Priority | Due Date   | Status      |
