Degraded logging performance
Affected: Nango Cloud Health
Timeline · 2 updates
- investigating Mar 07, 2025, 12:37 AM UTC
Our platform logging system is experiencing some slowdown and intermittent failure, resulting in lost messages. We are investigating.
- resolved Mar 07, 2025, 01:30 AM UTC
We have identified the root cause of the issue. The sharding for our log database was too small, creating a bottleneck. During the incident, syncs and actions were slower, but logging was not on the critical path. Only some log messages have been lost.
Downtime
Affected: Nango Cloud Health
Timeline · 2 updates
- investigating Mar 03, 2025, 01:50 PM UTC
Downtime: API/dashboard down, syncs/actions errors.
- resolved Mar 03, 2025, 02:05 PM UTC
Downtime: resolved. Root cause: a table from the main database had grown very large. A database client used for Business Intelligence performed an exact count on this table, locking the database. Mitigation: the database client now points to a read replica. The large table is being cleaned up.
