## Summary

Census reported a critical Sync Engine outage starting 2025-01-30 02:59 UTC: a networking misconfiguration sent database requests from unadvertised IPs, causing syncs to fail for customers whose databases rejected those IPs. Census rolled back to a previous configuration and resolved the incident at 2025-01-30 03:31 UTC; the reported duration was 31 min. _(machine-written, sol)_
## Timeline of updates

- **investigating** 2025-01-30 02:59 UTC: Due to a networking misconfiguration, requests originating from Census's database access service are originating from IPs that we have not previously advertised. If your database is configured to reject requests that are not from Census' IP addresses, syncs will start failing. We are investigating the root cause of the issue and it is our intent to restore service from the original IP addresses; we do not expect customers to need to reconfigure their databases at this time. More updates will be posted here.
- **identified** 2025-01-30 03:12 UTC: We have identified the root cause and are applying a fix to the networking configuration.
- **monitoring** 2025-01-30 03:24 UTC: We have rolled back the service to a previous configuration and we are monitoring our system to ensure database / warehouse connectivity returns to normal levels.
- **resolved** 2025-01-30 03:31 UTC: This incident has been resolved.
