19. Resolved May 4, 04:40 PM UTC

    On 2026-05-04 at 3:37:17 PM UTC we detected increased latency on issues resulting in timeouts, and elevated 500 errors on webhooks. A scheduled workload drove high utilization on the primary host of a critical datastore, saturating the connection pool. We paused the job to mitigate the problem at 4:40:05 PM UTC and have implemented measures to prevent recurrence.
