Starting from 13:00 UTC June 1, 2026, to 00:17 UTC June 2, 2026, multiple services experienced delayed job processing due to increased latency in our background job queue service. The root cause was insufficient queue processing capacity to handle a large week-over-week increase in total job traffic.

Users saw up to 90 minutes of delay in billing usage updates, 30 minutes of delay for webhook notifications to show, and 15 minutes of delay to see email notifications. Mitigation involved scaling up our background job service capacity to handle the spike in job traffic.

We have added queue capacity monitoring to our background job queue service to stay ahead of weekly growth patterns and to reduce time to detect in the future.
