Fast Incident Triage for Lab and Production

A short triage model to reduce mean time to recovery when network automation fails.

Three-phase triage model

Use this order every time:

1. Scope: identify impacted services and blast radius.
2. Stabilize: stop automation loops and prevent new writes.
3. Recover: rollback or patch, then resume controlled traffic.

Data you always collect

• Last successful deployment id.
• Change diff for affected nodes.
• Error rates and latency by region.
• Queue lag if message broker is used.

Team rule

One person drives the timeline, one person validates rollback, one person communicates status.
