By use case
Kill Switches
Mitigate production incidents in seconds by disabling unstable behavior at runtime while root-cause analysis continues.
When to use this playbook
- Error rate spikes after a rollout and a full redeploy would take too long.
- Downstream systems are unstable and load must be reduced immediately.
- You need environment-specific mitigation without reverting unrelated changes.
Incident response sequence
- 1. Identify affected flag or segment. Scope impact quickly using telemetry and recent change history.
- 2. Disable or retarget immediately. Turn off the risky path globally or isolate to safe cohorts.
- 3. Confirm recovery metrics. Validate latency, errors, and saturation have returned to baseline.
- 4. Document and prevent recurrence. Capture what happened and encode safer rollout checkpoints.
