GitHub的一些服务中断

2026年9月15日，协调世界时05:45至09:50期间，GitHub Copilot中的Claude Fable 5.1模型经历了间歇性可用性下降，平均错误率为2.8%。在每隔约45分钟重复出现的短暂15分钟时段内，Claude Fable 5.1的可用性最高下降至约40%，随后完全恢复。其他Copilot模型未受影响。用户可以继续使用其他模型或“Auto”模式工作。<br /><br />原因是上游模型提供商出现问题，在过载时间歇性拒绝请求。GitHub与该提供商合作，后者确认并在协调世界时9:50解决了根本问题，此后模型恢复持续正常可用。在确认恢复后，我们于协调世界时11:17解决了该事件。<br /><br />为降低再次发生和客户影响的可能性，GitHub正在审查按模型可用性告警和产品内自动回退机制，以便对降级模型的请求能更快转移到健康的替代模型。

原文On September 15, 2026, between 05:45 and 09:50 UTC, the Claude Fable 5.1 model in GitHub Copilot experienced intermittently degraded availability, with an average error rate of 2.8%. During brief recurring 15 minute periods that recurred every ~45 minutes, availability for Claude Fable 5.1 dropped to a maximum of ~40% before recovering completely. Other Copilot models were not affected. Users could continue to work with a different model or with 'Auto'.<br /><br />The cause was an issue with an upstream model provider that intermittently rejected requests while overloaded. GitHub worked with the provider, who acknowledged and then resolved the underlying issue at 9:50 UTC, after which the model returned to constant normal availability. Once recovery was guaranteed, we resolved the incident at 11:17 UTC.<br /><br />To reduce the chance of recurrence and customer impact, GitHub is reviewing per-model availability alerting and automatic in-product fallback so that requests to a degraded model can shift to a healthy alternative more quickly.

我们上游模型提供商的问题已解决，Claude Fable 5.1 现已在 Copilot 产品和 IDE 界面中恢复可用。<br /><br />我们将继续监控以确保稳定性，但缓解措施已完成。

原文The issues with our upstream model provider have been resolved, and Claude Fable 5.1 is once again available in Copilot products and IDE surfaces.<br /><br />We will continue monitoring to ensure stability, but mitigation is complete.

我们继续监控影响某些 Copilot 产品和集成开发环境中 Claude Fable 5.1 的间歇性错误。面向客户的指标已恢复，我们正在等待上游提供商确认该问题不会再次发生。在此期间，客户可以选择其他模型或 Auto。

原文We continue to monitor intermittent errors affecting Claude Fable 5.1 in some Copilot products and integrated development environments. Customer-facing metrics have recovered, and we are awaiting confirmation from our upstream provider that the issue will not recur. Customers can select another model or Auto in the meantime.
