Microsoft sees no link between US flight ground stop and its services
Microsoft also faced a separate worldwide outage affecting its email and other online services, which it blamed on servers going offline.
Microsoft said on Friday it had seen no sign that a nationwide US flight ground stop was tied to its services, Turkey's state-run news agency Anadolu Agency reported.
The company made the statement on X, the social media platform, after the Federal Aviation Administration halted flights across the country.
The FAA stopped flights following a telecommunications outage affecting Air Route Traffic Control Centers, and it described the halt as a precautionary measure.
Microsoft was dealing with a separate worldwide outage at the same time that affected its email and other online services.
The company blamed that disruption on several servers that unexpectedly went offline, which put extra strain on the remaining systems.
The FAA said every flight had been accounted for and that international flights would be handled on a case-by-case basis.
US Transportation Secretary Sean Duffy said FAA technicians were investigating a "communication issue" and that further updates would follow as information became available.
Homeland Security Secretary Markwayne Mullin told reporters he saw no reason to believe the ground stop was connected to the Microsoft service outage.
The FAA is the US federal agency that regulates civil aviation and runs the country's air traffic control system, while Microsoft operates cloud and email services used by businesses and governments worldwide.
