Incident with Actions

1. 已解决 · 22:49

   On October 5, 2026, between 18:48 and 22:49 UTC, GitHub Actions and Hosted Runners experienced degraded performance. Over the full incident, 14.3% of workflow runs using GitHub-hosted runners and 26.5% of individual GitHub-hosted jobs did not start within five minutes. <br /><br /> <br />During the roughly 90-minute period of highest impact, 47.0% of workflow runs using GitHub-hosted runners failed and 71.9% of GitHub-hosted jobs did not start within five minutes, while existing Pages sites continued to serve normally. A portion of customers also encountered intermittent errors in repository lists, licensing and billing pages, and some Copilot features. Self-hosted runners were not affected. <br /><br /><br />The incident was caused by a partial networking failure that disrupted connectivity between one of our on-premises datacenter regions and a subset of cloud-hosted regional database and storage services. <br /><br /><br />We mitigated the incident by shifting database and storage traffic to healthy regions and endpoints and increasing capacity for affected compute services. GitHub Actions and Hosted Runners recovered by 21:54 UTC, and all affected services recovered by 22:49 UTC. <br /><br /> <br />We are partnering with our cloud provider to understand the network failure and identify improvements to network-path resilience, detection, and recovery for similar incidents.

   We have applied mitigations to address GitHub Actions failures. Queued jobs are clearing, new jobs are not delayed, and we expect full runner recovery shortly. We continue to monitor for full recovery and are working to mitigate ongoing issues affecting other services, including access to repository lists, licensing, and billing pages.
