- This incident has been resolved. Thank you for your patience and understanding as we addressed this issue. A detailed root cause analysis will be shared as soon as it is available.
+ On November 9, 2026, from 09:23 to 11:40 UTC, one of our job queue clusters was degraded, delaying webhook deliveries, Actions workflow runs, and Dependabot and dependency graph updates. Until mitigation at 10:37 UTC, an average of 26% of webhook deliveries were delayed, peaking at 30%, and the backlog cleared by 11:40 UTC. Some deliveries were delayed by up to 3.5 hours, and delays for a small share began as early as 01:00 UTC. Actions skips events older than 30 minutes, so some workflow runs did not start. The incident was caused by a degraded host that had slowed one of the cluster's Kafka brokers since November 7. The broker stopped reporting the metrics our alerts rely on, so we did not identify it until it stalled the cluster on November 9. We mitigated the incident by removing the broker from service. We have since added an alert that pages us within 30 minutes when a host slows a broker this way, so we can remove the broker before it affects customers.
