微软周四表示，意外不可用的服务器而非用户流量激增，是导致其 Microsoft 365 服务在多个地区出现大范围连接问题的原因。
Microsoft said Thursday that unexpectedly unavailable servers, rather than increased user traffic, were behind widespread connectivity problems affecting its Microsoft 365 services across multiple regions.
微软 365 状态在美社交媒体平台 X 上的最新更新称，中断给剩余基础设施带来了额外压力。
In its latest update on US social media platform X, Microsoft 365 Status said the outages had placed additional strain on the remaining infrastructure.
“我们确定负载升高并非由流量增加驱动，而是由多台服务器意外不可用导致，”公司表示，并补充说正在努力安全地将受影响的服务器恢复上线。
“We determined the elevated load isn't driven by an increase in traffic, but by a number of servers being unexpectedly unavailable,” the company said, adding that it was working to safely bring the affected servers back online.
此次中断影响了对 Exchange Online 邮箱的访问，并可能波及其他 Microsoft 365 服务，用户通过各种访问方式均报告了连接问题。
The disruption affected access to Exchange Online mailboxes and potentially other Microsoft 365 services, with users reporting connectivity problems through various access methods.
微软表示，已暂停所有部署，将流量从受影响的基础设施重定向，并重启了受影响的服务器，作为恢复工作的一部分。
Microsoft said it had paused all deployments, redirected traffic away from affected infrastructure and restarted impacted servers as part of its recovery efforts.
此前，公司报告称多个地区的基础设施负载升高，并正在跨其全球网络重新分配连接流量以缓解中断。
Earlier, the company reported elevated infrastructure loads across multiple regions and said it was redistributing connection traffic across its global network to ease the disruption.
