Slack Thread: Notification Service Follow-up 13

Date: 2026-05-30 Channel: #release-checkout Service: Notification Service Incident Reference: INC-2025-503 Jira Reference: ACME-5013 GitHub Reference: GH-5017

Jordan Kim: We are reviewing INC-2025-503 for Notification Service. The main concern is whether the remediation in ACME-5013 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 Notification Service.

Devon Patel: Please make sure GitHub item GH-5017 includes contract tests for API API-NOTIFICATION-02 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-5013 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
