Microsoft's Global Outage May Be Worse Than Amazon's Or Crowdstrike's, Expert Says

A global Microsoft 365 outage that began midday Thursday and continued into Friday morning disrupted email, cloud and AI services for businesses, hospitals, police departments and schools, with Microsoft extending its email timeout to 48 hours to preserve delayed mail. Ciaran Martin, the former head of the UK's National Cyber Security Centre, told NBC News the disruption looks like "one of the biggest outages of all time" and possibly worse than the recent Amazon Web Services and CrowdStrike incidents. Microsoft, whose paid Microsoft 365 commercial subscriptions exceeded 450 million as of January, reported broader improvements in North America, sustained improvements across much of Europe and encouraging recovery signals in Asia Pacific, while warning some users may still see intermittent access issues or delayed email delivery.

An anonymous reader quotes a report from Ars Technica: A global outage taking down a wide range of Microsoft 365 services remains ongoing Friday morning. The outage started midday Thursday, impacting users of Microsoft email, cloud, and AI services. Microsoft has documented the full list of services impacted by the error, while moving early Friday morning to protect customers around the world from losing emails during the extended disruptions. "Recovery actions are ongoing," the Microsoft 365 Status account confirmed on X. "To help preserve delayed mail during this event, we've extended email timeout to 48 hours." Similar to recent world-shaking outages of widely used tech like Amazon Web Services and CrowdStrike, the Microsoft disruption looks like "one of the biggest outages of all time," Ciaran Martin, the former head of the UK's National Cyber Security Centre, told NBC News. Possibly even "worse," he suggested. Businesses, hospitals, police departments, and schools were among those scrambling to work around the outage. In Japan, it disrupted government IT infrastructure, according to deputy chief cabinet secretary Masanao Ozaki. NBC's report documented various harms, noting that "few public bodies were immune from the outage." In some cases, doctors couldn't send patients "important" updates on medication changes or follow-up care. The financial sector suffered, too, with people blocked from making bank transfers since they couldn't receive verification codes. Justice systems were also hobbled. The Supreme Court in the Philippines saw its legal work derailed, NBC reported. And one US sheriff's office in Colorado reported that the outage made it difficult for people to post bond for prisoners' immediate release. It's unclear how many users were affected, but Microsoft estimated in January that the total number of paid Microsoft 365 commercial subscriptions exceeded 450 million. Microsoft's most recent updates confirmed that it's seeing "broader improvements in North America, sustained improvements across much of Europe, and encouraging recovery signals in Asia Pacific." "Some users may still experience intermittent access issues or delayed email delivery as mitigation continues across remaining affected infrastructure," Microsoft said. "Our focus remains on stabilizing recovered infrastructure, completing mitigation in remaining impacted areas, and reducing delayed email queues and backlogs while we validate service consistency across connection methods."
