Slack Thread: Authentication Service Follow-up 38

Date: 2025-09-07 Channel: #sre-ops Service: Authentication Service Incident Reference: INC-2025-108 Jira Reference: ACME-1018 GitHub Reference: GH-1002

Noah Garcia: We are reviewing INC-2025-108 for Authentication Service. The main concern is whether the remediation in ACME-1018 also covers downstream impact to Checkout Service and Billing Service.

Elena Rossi: I checked traces for Authentication Service, Inventory Service, and Notification Service. The correlation IDs line up with the incident timeline, but the highest error rate stays inside Authentication Service.

Sam Rivera: Please make sure GitHub item GH-1002 includes contract tests for API API-AUTHENTICATION-03 and an update to the runbook.

Jordan Kim: Agreed. I will add release readiness notes, dashboard screenshots, and a rollback checkpoint before this goes to canary.

Maya Chen: Decision: keep ACME-1018 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
