The FAA has lifted the nationwide ground stop for U.S. Airports, per btpm.org. The advisory, issued at 20:53 UTC on Nov 13 and lasting about four hours, halted all departures and managed inbound flights case by case.

The ground stop was triggered by an air traffic control communications outage, according to Reuters and PBS reports. The FAA cited 'frequency issues' as the cause, with no indication of a cyberattack or external interference.

The disruption caused nearly 5,000 flights to be cancelled, according to Business Insider and NY Post reports.
