Slack Thread: Authentication Service Follow-up 27

Date: 2026-04-24 Channel: #release-checkout Service: Authentication Service Incident Reference: INC-2025-107 Jira Reference: ACME-1007 GitHub Reference: GH-1011

Jordan Kim: We are reviewing INC-2025-107 for Authentication Service. The main concern is whether the remediation in ACME-1007 also covers downstream impact to Checkout Service and Billing Service.

Maya Chen: 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.

Devon Patel: Please make sure GitHub item GH-1011 includes contract tests for API API-AUTHENTICATION-04 and an update to the runbook.

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

Noah Garcia: Decision: keep ACME-1007 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
