4. **Emergency Procedures**:
   - P0 outage: stop → diagnose → restart → rollback
   - Database recovery: restore from backup
   - Cache recovery: Redis RDB restore
   - Disk space: log rotation, cleanup
   - Memory pressure: service restart
   - Time sync: force chrony sync

5. **Troubleshooting**:
   - High API Gateway latency → check Redis, rate limits, DB
   - Order submission failures → check validation, risk limits, kill switch
   - JWT auth failures → check Redis, rotate secret
