操作运行在启动时遇到故障

2026年7月13日，UTC时间13:11至13:53期间，部分客户在启动和运行GitHub Actions工作流时遇到故障，这也影响了依赖Actions的Copilot云代理会话和GitHub Pages构建。在事件高峰期，30%的Actions任务未能启动，2%的任务延迟超过5分钟。<br /><br />该事件由内部自动缩放组件中的配置更改触发，该组件包含过时的容量阈值。这导致一个关键的Actions服务缩容至低于所需基线，减少了工作流处理的容量。我们识别出该回归问题，回滚了更改，并恢复了服务容量。新的工作流执行于UTC时间13:39恢复。在排空积压队列后，于UTC时间13:53完全恢复。<br /><br />为防止再次发生，我们已增加部署护栏，以验证自动缩放输入为最新状态，并在应用自动缩放更改前检测计划与实际缩放状态之间的偏差。

原文On July 13, 2026, between 13:11 and 13:53 UTC, some customers experienced failures starting and running GitHub Actions workflows, which also affected Copilot cloud agent sessions and GitHub Pages builds since they depend on Actions. During the peak of the incident, 30% of Actions jobs failed to start and 2% were delayed more than 5 minutes. <br /><br />The incident was triggered by a configuration change in an internal autoscaling component that contained outdated capacity threshold values. This caused a critical Actions service to scale below its required baseline, reducing capacity for workflow processing. We identified the regression, rolled back the change, and restored service capacity. New workflow executions recovered by 13:39 UTC. Full recovery was reached by 13:53 UTC after the queued backlog was drained. <br /><br />To prevent recurrence, we have added deployment guardrails to validate that autoscaling inputs are current and to detect drift between planned and live scaling state before autoscaling changes are applied.
