Copilot Code Review 无法完成审查

2026年9月28日，协调世界时19:23至22:08之间，Copilot Code Review服务出现降级，所有环境中的拉取请求审查均未能完成。平均而言，约70%的请求审查未能完成。在此期间请求的审查没有自动重试，用户需要从其拉取请求中重新请求审查。这是由于依赖服务的一项变更导致Copilot Code Review完成审查所需的数据停止传输。审查完成本身是一个延迟信号，因为每个审查任务都需要时间启动和完成，因此检测影响所需的时间更长。<br /><br />我们通过回滚该变更缓解了此事件。<br /><br />我们正在努力为未能完成的审查添加更快的信号，添加确认Copilot Code Review端到端完成的部署验证，改进我们跟踪服务间内部依赖关系的方式，并使我们的部署管道更加可靠，以减少未来检测和缓解此类问题的时间。

原文On September 28, 2026, between 19:23 UTC and 22:08 UTC the Copilot Code Review service was degraded and pull request reviews did not complete in all environments. On average, approximately 70% of requested reviews did not complete. Reviews requested during this window were not automatically retried, and users needed to re-request a review from their pull request. This was due to a change in a dependent service that stopped delivering data Copilot Code Review needs to complete a review. Review completion is an inherently delayed signal, because each review job takes time to start and finish, so it took longer to detect the impact.<br /><br />We mitigated the incident by reverting the change.<br /><br />We are working to add a faster signal for reviews that fail to complete, add deployment validation that confirms a Copilot Code Review completes end to end, improve how we track internal dependencies between services, and make our deployment pipeline more reliable to reduce our time to detection and mitigation of issues like this one in the future.
