B. Emergency Procedures

Service Outage Response

1. Immediate Actions (0-5 minutes)

   • Acknowledge incident
   • Assess impact and severity
   • Notify stakeholders
   • Begin investigation

2. Short-term Actions (5-30 minutes)

   • Scale resources if needed
   • Activate fallback systems
   • Update status page

3. Resolution (30+ minutes)

   • Identify root cause
   • Implement permanent fix
   • Verify system recovery
   • Conduct post-mortem

Data Breach Response

1. Containment (0-1 hour)

   • Isolate affected systems
   • Preserve evidence
   • Notify security team
   • Begin forensic analysis

2. Assessment (1-24 hours)

   • Determine data exposed
   • Assess breach scope
   • Legal consultation
   • Regulatory notifications

3. Recovery (24+ hours)

   • Implement security fixes
