Microsoft users around the world report widespread outages

Banks, airlines, TV stations and health systems in countries around the world that rely on Microsoft's 365 apps reported widespread outages Friday. Thousands of flights and train services were cancelled in the U.S. and Europe, and there were disruptions to many other public and retail services.

Microsoft 365 said on social media that it was "investigating an issue impacting users ability to access various Microsoft 365 apps and services" and that things were improving as the company worked to "reroute the affected traffic to healthy infrastructure."

American Airlines, Delta and United Airlines said all pending flight departures were grounded. American Airlines said this was due to "a technical issue with CrowdStrike" that it said was impacting multiple airlines, and that the company was in contact with its planes currently in flight.
