用托管跑步者的动作中断

2026年7月22日，UTC时间19:36至22:04期间，GitHub Actions在GitHub托管的运行器上遇到了作业启动延迟和失败的问题。该事件由负责配置托管运行器的后端数据服务处于不健康状态引起，导致部分工作负载无法获取运行器。在事件的大部分时间里，托管运行器上约15%的工作流运行延迟超过5分钟，而约1%的工作流未能启动。<br /><br />在UTC时间21:49，我们恢复了后端数据复制系统的健康状态，使配置得以恢复，并清空了积压的工作流。随后，服务性能恢复至预期水平。我们正在提升配置服务的弹性、工作负载分布和容量平衡，以减少类似事件发生的可能性和影响。

原文On July 22, 2026, between 19:36 UTC and 22:04 UTC, GitHub Actions experienced delayed and failed job starts on GitHub-hosted runners. The incident was caused by an unhealthy state in a backend data service responsible for provisioning hosted runners, preventing runner acquisition for a subset of workloads. During most of the incident, approximately 15% of workflow runs on hosted runners were delayed by more than 5 minutes, while roughly 1% failed to start.<br /><br />At 21:49 UTC, we restored the health of the backend data replication system, allowing provisioning to recover and the accumulated workflow backlog to drain. Service performance then returned to expected levels. We are improving provisioning-service resiliency, workload distribution, and capacity balancing to reduce the likelihood and impact of similar incidents.
