不只是你一个人遇到问题。微软365商业版和企业版服务周四发生重大故障，导致这款热门云办公套件的用户无法登录账户。
It’s not just you. Microsoft’s 365 business and enterprise services suffered a major outage on Thursday, preventing users of its popular cloud suite from accessing their accounts.
美国东部时间周四上午10点40分左右，微软在X平台的365状态页面上发帖称，正在“调查有关北美用户访问或使用Microsoft Teams功能时遇到问题的报告”。到美国东部时间下午1点前，微软表示已获悉“美洲地区用户通过多种连接方式访问Exchange Online邮箱出现问题”。微软随后称，其网络也“在多个区域出现负载升高，这可能是导致连接错误的原因之一”，但该问题与服务器下线有关，并非流量增加所致。
Around 10:40 am ET on Thursday morning, Microsoft posted on its 365 status page on X that it was “investigating reports of users experiencing issues when accessing or using Microsoft Teams functionality in North America.”By just before 1pm ET, it said it was aware of “issues accessing Exchange Online mailboxes through multiple connection methods in the Americas.”Microsoft later said that its network was also “experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors,” but that the issue was related to servers going offline, not due to increased traffic.
大约一小时后，微软表示已“开始在全球更广泛的基础设施中重新分配连接流量，以帮助平衡负载”，并正在“积极寻求一切途径来减轻影响”。微软写道：“我们已暂停所有部署。我们正在将更多流量从受影响的基础设施上转移出去，并正在重启受影响的服务器以使其恢复服务。”
Around an hour later, Microsoft said it had “begun redistributing connection traffic across our broader worldwide infrastructure to help balance the load” and was “aggressively pursuing all pathways to reduce impact.”“We've paused all deployments. We're moving additional traffic off the affected infrastructure, and we're restarting affected servers to return them to service,” Microsoft wrote.
微软在状态页面的更新中表示，受影响的服务可能包括Exchange Online、Microsoft Teams、SharePoint Online、Microsoft Copilot 365和Microsoft Defender XDR。
In an update on its status page, Microsoft said impacted services may include Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot 365, and Microsoft Defender XDR.
微软一位发言人向《连线》杂志发表声明称：“我们已获悉并正在调查用户反映的Microsoft 365服务问题，主要是Exchange Online的问题。感谢客户的耐心等待，我们正努力尽快恢复服务。”在服务正常运行时间追踪网站Downdetector上，故障报告在美国东部时间下午1点15分左右开始减少，此前中午前后报告Outlook及其他Microsoft 365产品问题的用户数量曾大幅激增。
“We are aware and investigating reports of users experiencing issues with Microsoft 365 services, primarily issues with Exchange Online,” a Microsoft spokesperson tells WIRED in a statement. “We appreciate our customer's patience while we work to restore services as soon as possible." Outage reports on the service uptime tracking website Downdetector began falling around 1:15 pm ET after a large spike in users reporting issues with Outlook and other Microsoft 365 products around noon.
目前尚不清楚中断何时结束，也不清楚其原因。微软在美东时间下午3点前发布在X平台上的状态更新中表示，“一个问题”正“导致服务器无法通过自动健康检查并变得不可用”，但该公司正试图重启系统，希望能使其重新上线。
It is currently unclear when the outage may be over or what its cause may be. In a status update on X posted just before 3 pm ET, Microsoft said “a problem” was “causing servers to fail automated health checks and become unavailable” but that it’s attempting to reboot its systems to hopefully bring them back online.
云服务中断频繁发生，其原因可能多种多样。配置错误、域名系统解析问题以及网络攻击都可能导致连接错误。目前没有迹象表明网络攻击导致了此次微软中断。
Outages in cloud services occur frequently, and their causes can vary. Configuration errors, resolution issues with the Domain Name System, and cyberattacks can all cause connection errors. There is currently no indication that a cyberattack caused the current Microsoft outage.
虽然微软大规模中断相对罕见，但绝非前所未有。2024年7月，安全公司CrowdStrike的一个损坏更新导致微软Azure服务瘫痪数小时，因企业无法正常运营而造成了数以百万计美元的收入损失。
While major Microsoft outages are relatively rare, they are far from unprecedented. In July 2024, a corrupted update from the security firm Crowdstrike knocked out Microsoft Azure services for hours, causing untold millions of dollars in lost revenue due to companies’ inability to function as normal.
