Microsoft's massive M365 outage stretches past 12 hours as its fixes keep failing
Hasn't completely ruled out cyberattack as cause of incident that's damaged Exchange Online and services that rely on it
The "Microsoft long weekend" in Australia has turned into a prolonged disruption of Microsoft 365 services, affecting organizations that rely heavily on the company's online platforms. The outage began on Thursday at 18:00 UTC, causing users to lose access to email, Teams meetings, cloud PCs, Copilot, and 15 other hosted services.
Microsoft initially attributed the issue to servers failing automated health checks, but later admitted their fixes were not successful. Despite attempts to resolve the problem, the situation remains unresolved, and Microsoft is now exploring various workstreams to pinpoint the root cause of the traffic surge and restore the backend servers.
As of now, the company is scaling up virtual machines and observing partial recovery across regions, but these actions have not yielded sustained results. Microsoft has also ruled out any malicious activity causing the outage, and it continues to pursue multiple strategies to identify and repair the affected infrastructure. The prolonged disruption has brought the possibility of a long weekend for both Australia and other nearby countries into question.
