Nationwide suspension of American outbound flights due to communications disruption.
The US Federal Aviation Administration (FAA) declared a state of emergency and ordered the suspension of outbound flights across the country, citing safety concerns.
This decision was first announced following a communications blackout at Chicago's O'Hare International Airport, and later expanded to a nationwide suspension of flights.
This incident happened while Microsoft's services also faced widespread disruption in dozens of countries since Thursday.
This disruption affected services such as Outlook, Teams and Copilot, and disrupted users' access to e-mail, business communications and some online services.
