Overview

What are Runbooks?

Runbooks are step-by-step operational guides that enable any engineer to execute complex procedures consistently and reliably. They are designed to be followed during high-stress situations when quick, accurate action is critical.

When to Use These Runbooks

  • During incidents: Follow the appropriate runbook for the failure type
  • During testing: Use runbooks to practice disaster recovery
  • During training: Familiarize new team members with procedures
  • During planning: Reference RTO/RPO targets for capacity planning

Decision Tree

Use this decision tree to select the appropriate runbook:

Is the entire infrastructure down?
├─ YES → Use Full DR Procedure
└─ NO → Continue

Is the database corrupted or inaccessible?
├─ YES → Use Database Restore
└─ NO → Continue

Is the backend service down or malfunctioning?
├─ YES → Use Backend Redeploy
└─ NO → Continue

Is the Stellar RPC node failing?
├─ YES → Use RPC Failover
└─ NO → Check component-specific documentation
