Procedure
Follow each step in order. Mark complete as you proceed.
1
Triage
Check the rate of 5xx responses per upstream in Grafana. If only one upstream is failing, route investigation to its owning team.
2
Mitigate
If the upstream is overloaded, enable circuit breaker via the runtime config. If a bad deploy is suspected, prepare for rollback.
3
Rollback
Use `sg deploy rollback api-gateway --ref <last-good>` to revert to the previous stable release.
