延迟启动操作运行

2026年7月9日，UTC时间03:29至13:39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，托管运行器上约有8%的工作流运行延迟超过5分钟，而约2%未能启动。<br /><br />在13:39 UTC，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，累积的工作流积压得以清空。随后服务性能恢复到预期水平。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 9, 2026, between 03:29 UTC and 13:39 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 8% of workflow runs on hosted runners were delayed by more than 5 minutes, while roughly 2% failed to start.<br /><br />At 13:39 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.

Actions、Pages builds、Copilot Cloud Agent和Copilot Code review均已恢复并得到缓解。<br /><br />我们正在持续监控以确保完全恢复，并调查受影响基础设施的健康状况。

原文Actions, Pages builds, Copilot Cloud Agent, and Copilot Code review have all recovered and are mitigated.<br /><br />We are continuing to monitor to ensure full recovery, and investigating the health of the affected infrastructure.

影响Actions和Pages的服务降级问题已得到缓解。我们正在持续监控以确保稳定性。

原文The degradation affecting Actions and Pages has been mitigated. We are monitoring to ensure stability.

我们正在持续监控Actions和Pages构建的缓慢恢复情况，系统正在处理大量积压任务。<br /><br />在系统恢复期间，客户可能会看到少量API和作业失败。<br /><br />在此事件期间，Copilot Cloud Agent和Copilot Code Review也未能启动约30分钟，我们正在监控恢复情况。<br /><br />整个事件期间，Pages始终可访问。

原文We are continuing to monitor slow recovery in Actions and Pages builds as the system works through the high volume of backlog.<br /><br />Customers may see a small rate of  API and job failures as the system is recovering.<br /><br />Copilot Cloud Agent and Copilot Code Review also failed to start for approximately 30 minutes during this incident, and we are monitoring recovery.<br /><br />Pages were accessible throughout the incident.

Actions 正经历可用性降级。我们正在继续调查。

原文Actions is experiencing degraded availability. We are continuing to investigate.

我们正在观察Actions和Pages的恢复情况。<br /><br />在约20分钟的时间段内，约96%的GitHub Actions在GitHub托管的运行器上无法启动，但现已恢复，我们正在看到任务正在处理中。<br /><br />在此期间，GitHub Pages构建也出现失败，但Pages仍然可以访问。<br /><br />我们将继续监控，确保完全恢复。

原文We're seeing Actions and Pages recovery. <br /><br />For a period of approximate 20 minutes ~96% of GitHub Actions runs on GitHub-hosted runners were failing to start, but has now recovered and we are seeing jobs processing.<br /><br />GitHub pages builds were also failing during that period, but Pages are still accessible.<br /><br />We are continuing to monitor for full recovery.
