Slack Thread: Checkout Service Follow-up 17

Date: 2025-11-25 Channel: #sre-ops Service: Checkout Service Incident Reference: INC-2025-207 Jira Reference: ACME-2017 GitHub Reference: GH-2001

Noah Garcia: We are reviewing INC-2025-207 for Checkout Service. The main concern is whether the remediation in ACME-2017 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 Checkout Service.

Sam Rivera: Please make sure GitHub item GH-2001 includes contract tests for API API-CHECKOUT-02 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-2017 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
