Slack Thread: Billing Service Follow-up 28

Date: 2026-02-14 Channel: #eng-incident Service: Billing Service Incident Reference: INC-2026-308 Jira Reference: ACME-3008 GitHub Reference: GH-3012

Maya Chen: We are reviewing INC-2026-308 for Billing Service. The main concern is whether the remediation in ACME-3008 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-3012 includes contract tests for API API-BILLING-01 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-3008 open until staging replay passes and the incident review confirms no unsupported customer-impact claims.
