By Microsoft is struggling to fix a global outage that has disrupted services for tens of thousands of users across 74 countries. Teams, Outlook, and AI assistant Copilot all went down due to what the company described as “connectivity problems.” After more than eight hours, Microsoft admitted that its attempts to restore services are “not taking as expected.” The company initially reported “positive results” from its fix before walking that assessment back.
We’re 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.

This is Microsoft’s latest in a pattern of major outages throughout 2026. According to Microsoft, its infrastructure is “experiencing elevated load across multiple regions.” That language typically indicates servers are under heavy strain and unable to handle normal traffic volumes. The company has not confirmed the root cause but stated the outage is unlikely to have resulted from a cyber-attack. However, one expert pushed back on that framing. Paul Spain from New Zealand-based advisory firm Gorilla Technology said that if this is not an attack, then it represents “incredible incompetence” that will cost millions of dollars in economic impact.
The scale of disruption is enormous. More than 430 million people use Microsoft 365 apps globally. Over 90% of Fortune 500 companies rely on Copilot, Microsoft’s AI chatbot. Between three and four million companies run their operations on Microsoft 365. Because the outage hit email, video conferencing, and AI tools simultaneously, affected businesses effectively lost an entire working day.
In Australia, one of the first countries to wake up to the outage, public services reported immediate consequences. Service NSW urged customers to delay visits and complete transactions online where possible. Northern Territory government services also went down. Hospitals reported clerical issues but confirmed that patient care remained unaffected. Some medical facilities returned to paper prescriptions as a workaround.
Cybersecurity expert Troy Hunt warned that the outage extends well beyond Microsoft’s direct users. Because Microsoft forms a massive part of the internet backbone, the disruption affects account verification, purchase confirmations, appointment communications, and access to third-party services that depend on Microsoft infrastructure. Hunt stressed that this outage reinforces the importance of businesses maintaining contingency plans for cloud service failures.
Microsoft has experienced multiple major outages in 2026 alone. In January, a 10-hour outage disrupted Exchange Online, Teams, and Outlook due to elevated service load during maintenance. In July, another widespread failure hit Azure and Microsoft 365 after a network failure in the West US region. Each incident follows a similar pattern of initial optimism from Microsoft followed by extended recovery timelines.
