Disaster Recovery Playbook

Template Overview

Surviving catastrophic cloud outages, regional network cuts, or cryptographic ransomware attacks requires unambiguous, battle-tested disaster recovery playbooks. The Disaster Recovery Playbook template documents recovery objectives, automated failover steps, communication trees, and validation runbooks in an immutable Markdown document.

# Enterprise Disaster Recovery Playbook — [System Name]

## 1. Disaster Classification & Activation Criteria
- **Scenario A (Regional Cloud Outage):** Complete loss of primary cloud availability zone or geographic region.
- **Scenario B (Ransomware / Hostile Compromise):** Unauthenticated cryptographic modification of database clusters.
- **Scenario C (DNS / Ingress Severing):** Global routing failure across primary CDN/edge proxies.
- **Declaration Authority:** DR playbook activated solely by [[Incident Commander]] or [[CISO]].

## 2. Step-by-Step Regional Failover Runbook
1. **Declare Disaster State:** Convene emergency incident bridge and issue executive notice.
2. **Sever Compromised Ingress:** Execute automated DNS traffic pause script (`./dr-scripts/sever-ingress.sh`).
3. **Verify Replica Data Parity:** Inspect secondary database replica WAL offset and transaction log integrity.
4. **Promote Secondary Replica:** Execute automated promotion script (`./dr-scripts/promote-replica.sh`).
5. **Route Edge Traffic:** Shift global Anycast DNS routing to secondary regional endpoint.
6. **Execute Synthetic Smoke Tests:** Validate authentication, document ingestion, and billing APIs.

## 3. Emergency Communication Tree & Stakeholder Escalation
| Role | Contact Channel | Primary Responsibility | SLA |
|---|---|---|---|
| **Incident Commander** | Out-of-band Signal Bridge | Tactical runbook execution | Immediate |
| **Comms Lead** | External Hosted Status Page | Customer public notifications | Within 15m |
| **Legal Counsel** | Dedicated Mobile Line | Regulatory and compliance briefing | Within 30m |
| **Executive Sponsor** | Executive Signal Channel | Board of Directors updates | Within 45m |

## 4. Post-Recovery Validation & Audit Sign-Off
- [ ] Verify 100% database write consistency and zero data corruption.
- [ ] Confirm automated backup snapshot generation resumes on promoted primary.
- [ ] Schedule formal blameless post-mortem review within 72 hours.

# Disaster Recovery Playbook — Core Auth & Ingestion

## 1. Drill Validation
Conducted quarterly disaster recovery simulation. Simulated complete catastrophic loss of primary EU region.

## 2. Observed Recovery Metrics
- Time to Declare: 2.1 minutes.
- Replica Promotion: 4.8 minutes.
- Global DNS Shift: 3.2 minutes.
- Total Realized RTO: 10.1 minutes (well within 15-minute SLA).
- Realized RPO: Zero data loss verified via cryptographic transaction logs.

## 3. Playbook Updates
Updated automated failover script to parallelize health check ping sweeps.

When to Use and When to Avoid

When to Use

• Use to document formal disaster recovery procedures for mission-critical infrastructure.
• Use during quarterly DR simulation drills and business continuity audits.
• Use to ensure operational procedures remain readable during complete cloud network blackouts.

When to Avoid

• Avoid for routine software bug triage sessions.
• Avoid for everyday feature sprint backlog reviews.
