跟进：微软为全球故障致歉，称成因出在早前网络扩容升级、与网络攻击无关，全面恢复尚无时间表

微软11月13日下午就11月12日开始、持续超过24小时的 Microsoft 365 全球故障公开致歉。微软在美东时间13时05分的社交平台发文中说，公司对这次事件给客户与合作伙伴造成的服务中断「深表歉意」，已经处理了底层问题，正在继续为其余客户与地区恢复服务。

微软同时给出初步成因：这次是技术问题，与网络攻击无关，也与超级智能（SI）智能体无关；问题出在早前一次网络扩容升级中引入的一个毛病，在近期一次网络变更之后浮现。微软说，复盘完成后将公布完整的事故报告，包括根本原因与改进措施。

恢复进度方面，微软说，因需求规模庞大，公司是逐步恢复服务、每一步都先验证稳定性，所以耗时较长，但有助于稳定恢复。按其服务健康页面，美东时间15时前后，包括 Microsoft 365 与 Outlook 在内的服务已显示「运行正常」；公司同时提醒，基础设施稳定期间仍在排空排队邮件并重新平衡流量，登录与访问可能先恢复，邮件投递与处理则还要继续追赶，目前仍没有全面恢复的时间表。

故障监测口径也显示报告量大幅回落：Downdetector 在美东时间14时50分收到约1,600宗 Outlook 问题报告，Microsoft 365 约700宗，而11月12日故障开始时 Outlook 报告曾达约13万宗、Microsoft 365 接近5万宗。这次故障自11月12日起波及 Outlook、Teams 等多项服务，GSM 此前已连续跟进。

Microsoft Apologizes for Global Outage, Blames an Issue From an Earlier Network Capacity Upgrade, and Gives No Time for Full Recovery

Microsoft on the afternoon of November 13 publicly apologized for the global Microsoft 365 outage that began on November 12 and lasted more than 24 hours. In a social media post at 1:05 p.m. Eastern, the company said it was "deeply sorry for the disruption this incident has caused our customers and partners," that it had addressed the underlying issue, and that it was continuing to restore service to the remaining customers and regions.

Microsoft also gave a preliminary cause: this was a technical issue, not related to a cyberattack or to super intelligence (SI) agents; the incident was introduced by an issue during an earlier network capacity upgrade that surfaced following a recent network change. The company said it would share a full post-incident report, including the root cause and defense-in-depth actions, once its review is complete.

On recovery, Microsoft said that given the scale of demand it restored services gradually, validating stability at each stage, which took longer but helped ensure a stable restoration. Its service health page showed services including Microsoft 365 and Outlook as "operational" around 3 p.m. Eastern. The company also noted that as infrastructure stabilizes it is still draining queued messages and rebalancing traffic, so sign-in and access may recover while delivery and processing continue to catch up, and it does not yet have an estimated time for full recovery.

Outage reports also fell sharply: Downdetector received about 1,600 Outlook problem reports at 2:50 p.m. Eastern and about 700 for Microsoft 365, down from about 130,000 Outlook reports and nearly 50,000 Microsoft 365 reports when the outage began on November 12. The outage has affected services including Outlook and Teams since November 12, and GSM has been following it continuously.
