GitHub的一些服务中断

2026年7月14日，GitHub Codespaces服务在两个时间段内出现降级——分别为UTC时间06:00至09:56，以及10:54至12:53——部分用户在创建新的codespaces时遇到了间歇性失败或延迟。影响集中在部分地理区域。在第一个时间段内，错误率平均为0.5%，峰值达到codespace创建请求的4.6%。第二个时间段更为显著，在受影响最严重的区域，峰值时约30%的codespace创建请求受到影响，随后恢复。两个时间段均由恶意行为者导致的codespace创建量意外激增引起，这消耗了受影响区域可用计算容量，且消耗速度超过了容量补充速度。<br /><br />我们通过识别并阻止过量创建流量的来源、减少受影响区域可消耗的资源，以及跨区域重新平衡流量以恢复容量，从而减轻了影响。每个时间段后，codespace创建成功率均恢复正常。<br /><br />我们正在努力增加自动化的低延迟控制措施，以限制异常的codespace创建，并加强我们的检测和防护机制，从而缩短未来对此类问题的检测和缓解时间。

原文On July 14, 2026, the GitHub Codespaces service was degraded during two periods — between 06:00 UTC and 09:56 UTC, and again between 10:54 UTC and 12:53 UTC — and some users experienced intermittent failures or delays when creating new codespaces. Impact was concentrated in a subset of geographic regions. During the first period, the error rate averaged 0.5% and peaked at 4.6% of codespace creation requests. The second period was more pronounced, peaking at approximately 30% of codespace creation requests in the most-affected region before recovery. Both periods were caused by an unexpected surge in codespace creation from an abusive actor that drained the available compute capacity in the affected regions faster than it could be replenished. <br /><br />We mitigated the impact by identifying and stopping the sources of the excess creation volume, reducing the resources that could be consumed in the affected regions, and rebalancing traffic across regions to restore capacity. Codespace creation success rates returned to normal after each period. <br /><br />We are working to add automated, low-latency controls to throttle abnormal codespace creation and to strengthen our detection and safeguards, so we can reduce our time to detection and mitigation of issues like this in the future.
