Resumo
On February 3, 2026, between 14:00 UTC and 17:40 UTC, customers experienced delays in Webhook delivery for push events and delayed GitHub Actions workflow runs. During this window, Webhook deliveries for push events were delayed by up to 40 minutes, with an average delay of 10 minutes. GitHub Actions workflows triggered by push events experienced similar job start delays. Additionally, between 15:25 UTC and 16:05 UTC, all GitHub Actions workflow runs experienced status update delays of up to 11 minutes, with a median delay of 6 minutes.
The issue stemmed from connection churn in our eventing service, which caused CPU saturation and delays for reads and writes, with subsequent downstream delivery delays for Actions and Webhooks. We have added observability tooling and metrics to accelerate detection, and are correcting stream processing client configuration to prevent recurrence.
