Duffy says a router an L3Harris contractor installed flooded the FAA's telecom network and caused the Nov. 13 nationwide ground stop
FlightAware counted more than 9,100 cancellations on Friday, Nov. 13, and more than 6,400 on Saturday, Nov. 14, above the FAA's forecast of 4,000 to 5,000 for Nov. 14.
On Friday, Nov. 13, the FAA halted every U.S. departure for more than four hours after a telecom failure disrupted the centers that handle high-altitude traffic. Thousands of flights were canceled or delayed.
ContextAviation consultant Andrew Charlton told the AP the stop affected about a quarter of the roughly 45,000 flights the U.S. runs each day. It was only the second nationwide ground stop (an order keeping every departure on the ground) since the Sept. 11, 2001, attacks, per the AP. The other came in January 2023, when the FAA's pilot-notice system failed. L3Harris has run the FAA's telecom network since 2002, under a contract its predecessor, Harris Corp., won that year. "We have one federal telephony infrastructure," Bedford said. "We don't have two, but one." Duffy blamed the age of the system: "It was the old legacy equipment. It failed. And listen, it's going to continue to fail."
