Slack Thread: Notification Service Follow-up 16

Date: 2025-07-17 Channel: #eng-incident Service: Notification Service Incident Reference: INC-2026-506 Jira Reference: ACME-5016 GitHub Reference: GH-5020

Priya Shah: We are reviewing INC-2026-506 for Notification Service. The main concern is whether the remediation in ACME-5016 also covers downstream impact to Checkout Service and Billing Service.

Noah Garcia: 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.

Elena Rossi: Please make sure GitHub item GH-5020 includes contract tests for API API-NOTIFICATION-01 and an update to the runbook.

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

Jordan Kim: Decision: keep ACME-5016 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
