GitHub的一些服务中断

从2026年6月26日23:40 UTC至2026年6月28日20:55 UTC，Copilot Cloud Agent出现性能降级。代理在报告进度、回复拉取请求评论或打开拉取请求时可能失败。受影响的内置工具调用平均错误率约为8%，每小时错误率峰值约为26%。<br /><br />此问题源于Copilot Cloud Agent运行时部署期间引入的一个回归，导致多个内置代理工具不可用。在许多情况下，受影响的工具调用静默失败，因此代理任务看似成功。这一监控缺口意味着识别故障所需的时间比预期更长。我们通过将运行时部署回滚到先前稳定版本来缓解此事件。<br /><br />我们已为此类工具可用性错误添加了监控和警报，以缩短检测时间。同时，我们正在为这些内置代理工具添加回归测试，并改进未来运行时推出的发布安全性，以避免类似问题。

原文From June 26, 2026 at 23:40 UTC through June 28, 2026 at 20:55 UTC, Copilot Cloud Agent was degraded. The agent could fail when reporting progress, replying to pull request comments, or opening pull requests. For affected built-in tool calls, the average error rate was approximately 8%, with hourly error rates peaking around 26%.<br /><br />This was due to a regression introduced during a Copilot Cloud Agent runtime deployment that caused several built-in agent tools to become unavailable. In many cases, the affected tool calls failed silently so agent jobs appeared to succeed. This monitoring gap meant it took longer than expected to identify the failure. We mitigated the incident by reverting the runtime deployment to the previously stable version.<br /><br />We've added monitoring and alerting for this class of tool-availability error to reduce time-to-detection. We're also adding regression tests for these built-in agent tools, and improving the shipping safety for future runtime rollouts to avoid similar issues.
