Incident Response Simulation

Format: Simulate a production incident and practice the response process.

Scenario: "At 3 AM, you receive an alert: the application is completely inaccessible."

Response steps:

1. Confirm the issue (Is it a false alarm?)
2. Assess impact (Who is affected? How severe?)
3. Communicate (Notify the team, update the status page)
4. Diagnose (Check logs, check monitoring)
5. Fix (Rollback? Fix code? Restart service?)
6. Verify (Is the problem actually resolved?)
7. Post-mortem (Why did it happen? How to prevent it?)
