Incident Response Runbook

Overview

This runbook provides procedures for responding to incidents in the DeFi Oracle Meta Mainnet (ChainID 138) network.

Incident Classification

Severity Levels

• P0 - Critical: Network down, data loss, security breach
• P1 - High: Service degradation, validator failures
• P2 - Medium: Performance issues, non-critical service failures
• P3 - Low: Minor issues, informational alerts

Incident Response Process

1. Detection

• Monitor alerts from Prometheus/Alertmanager
• Check Grafana dashboards
• Review logs in Loki
• Monitor external reports

2. Triage

• Classify severity
• Identify affected components
• Assess impact
• Assign incident owner

3. Response

• Follow runbook procedures
• Document actions taken
• Communicate with stakeholders
• Escalate if needed

4. Resolution

• Verify resolution
• Document root cause
• Update runbooks if needed
• Conduct post-incident review

Common Incidents

Network Outage

Symptoms:

• No blocks being produced
• Validators not responding
• RPC endpoints unavailable

Response:

1. Check validator status: kubectl get pods -n besu-network -l component=validator
2. Check logs: kubectl logs -n besu-network <validator-pod>
3. Check network connectivity
4. Restart validators if needed: kubectl rollout restart statefulset/besu-validator -n besu-network
5. Verify block production: curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' http://<rpc-endpoint>

Validator Failure

Symptoms:

• Validator pod not running
• Validator not producing blocks
• High error rate in logs

Response:

1. Check pod status: kubectl describe pod <validator-pod> -n besu-network
2. Check logs: kubectl logs <validator-pod> -n besu-network
3. Check resource usage: kubectl top pod <validator-pod> -n besu-network
4. Restart validator if needed
5. Check validator keys in Key Vault
6. Verify network connectivity

RPC Endpoint Issues

Symptoms:

• RPC endpoints not responding
• High latency
• Error rates increasing

Response:

1. Check RPC pod status: kubectl get pods -n besu-network -l component=rpc
2. Check Application Gateway status
3. Check rate limiting
4. Scale RPC nodes if needed: kubectl scale statefulset/besu-rpc --replicas=5 -n besu-network
5. Check network policies
6. Verify backend connectivity

Oracle Update Failures

Symptoms:

• Oracle not updating
• High error rate in oracle publisher
• Circuit breaker open

Response:

1. Check oracle publisher status: kubectl get pods -n besu-network -l app=oracle-publisher
2. Check logs: kubectl logs <oracle-pod> -n besu-network
3. Check circuit breaker state
4. Verify data sources
5. Check RPC connectivity
6. Verify private key access
7. Restart oracle publisher if needed

Security Incident

Symptoms:

• Unauthorized access attempts
• Unusual network traffic
• Suspicious transactions

Response:

1. Isolate affected components
2. Preserve logs and evidence
3. Notify security team
4. Review access logs
5. Check for compromised keys
6. Rotate keys if needed
7. Update security policies

Escalation

Escalation Path

1. On-Call Engineer: Initial response
2. Team Lead: For P1/P0 incidents
3. Engineering Manager: For critical incidents
4. CTO: For security incidents

Communication

• Update incident status in Slack/PagerDuty
• Notify stakeholders via email
• Post updates to status page
• Conduct post-incident review

Post-Incident Review

Review Process

1. Document incident timeline
2. Identify root cause
3. Document lessons learned
4. Update runbooks
5. Implement improvements
6. Share findings with team

Review Template

• Incident: Brief description
• Timeline: Key events and timestamps
• Root Cause: What caused the incident
• Impact: What was affected
• Resolution: How it was resolved
• Lessons Learned: What we learned
• Action Items: What needs to be done

Contacts

• On-Call: Check PagerDuty
• Security Team: security@d-bis.org
• Engineering Lead: engineering@d-bis.org
• Emergency: +1-XXX-XXX-XXXX
