   v2 delta generation service experienced failures from ~21:15 UTC Feb 9 to ~10:00 UTC Feb 10, 2026, due to a missing configuration dependency during a logic change. **Impact:** * v2 delta generation requests failed to complete * No data loss or security impact **Root Cause:** Recent logic changes were deployed without the required accompanying configuration update, preventing the service from completing v2 delta requests. **Resolution:** The logic changes were rolled back, restoring the service to its previous stable state. **Follow-up Actions:** * Prepare and deploy the permanent fix We apologize for the disruption and any inconvenience this caused. We are committed to improving our processes to prevent similar issues in the future.
