## Timeline of updates

- **resolved** 2025-09-09 12:00 UTC: Impact: A subset of clients connecting through the eu-central-1 region experienced increased error rates and timeouts when accessing certain databases. Clients in us-west-2 were also briefly affected. The issue was limited in scope and did not impact other regions. Root Cause: During an ongoing migration to improve database routing reliability, a configuration step was applied inconsistently across regions.  Resolution: Our monitoring alerted us within minutes, and the migration was promptly rolled back for the affected regions. Service definitions were restored, and normal database connectivity resumed by 15:08 UTC. Next Steps: We are reviewing our migration process to ensure consistency across all regions and adding additional safeguards to prevent similar issues in the future.
