Slack Thread: Billing Service Follow-up 21

Date: 2025-11-29 Channel: #sre-ops Service: Billing Service Incident Reference: INC-2025-301 Jira Reference: ACME-3001 GitHub Reference: GH-3005

Maya Chen: We are reviewing INC-2025-301 for Billing Service. The main concern is whether the remediation in ACME-3001 also covers downstream impact to Checkout Service and Billing Service.

Devon Patel: 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 Billing Service.

Priya Shah: Please make sure GitHub item GH-3005 includes contract tests for API API-BILLING-02 and an update to the runbook.

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

Elena Rossi: Decision: keep ACME-3001 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
