Microsoft Outage
Microsoft Outage Hits 365 and Azure Services, Disrupts Airlines and Businesses Worldwide
October 29, 2025 — A widespread Microsoft outage on Wednesday caused major disruptions across several of the company’s cloud and productivity services, impacting users and businesses that rely on its Azure and Microsoft 365 platforms.
Microsoft’s official 365 Status account confirmed that the issue stemmed from an ongoing Azure outage, which created “downstream impacts” on other connected services. Users across the U.S., Europe, and parts of Asia reported being unable to access Outlook, Teams, and other Microsoft tools throughout the day.
The disruption also rippled beyond individual users. Alaska Airlines said it was “experiencing a disruption to key systems,” including websites and booking platforms, due to Azure-related issues. The airline noted that several of its digital services, along with those of Hawaiian Airlines, are hosted on Microsoft’s cloud infrastructure.
The incident comes just over a week after a similar issue hit Amazon Web Services (AWS), which experienced a large-scale service interruption on October 20. That outage temporarily affected numerous websites and apps as AWS reported “increased error rates” for its EC2 cloud service.
According to Canalys, AWS continues to lead the cloud infrastructure market with 32% share as of the first quarter, followed by Microsoft Azure at 23% and Google Cloud at 10%. However, both Azure and Google Cloud have been expanding rapidly, fueled by a surge in artificial intelligence workloads and enterprise adoption.
This week’s outage arrives at a critical time for the tech giants, as Microsoft, Alphabet (Google’s parent company), and Amazon are all set to report their quarterly earnings. Microsoft and Alphabet will release their results Wednesday after market close, while Amazon follows on Thursday.
This is not the first time Microsoft’s cloud ecosystem has faced reliability challenges. In March 2025, a weekend-long Microsoft outage left tens of thousands of users locked out of their Outlook email and other Office applications.
As of Wednesday evening, Microsoft engineers said they were continuing to work on restoring full service and monitoring the stability of affected systems.
