CHICAGO, US - NOVEMBER 13: A view of an information board at the Chicago O’Hare International Airport, filled with waiting passengers on November 13, 2026, after the Federal Aviation Administration ordered a nationwide ground stop on all departing flights following a communication issue impacting air traffic control centers across the United States. With departures held until further notice, travelers waited in crowded terminals as delays mounted, while arriving flights continued to land normally.

Terrence O'Brien is the Verge’s weekend editor. He’s covered the tech industry for over 18 years and knows a thing or two about synths.

At a press conference today, Transportation Secretary Sean Duffy said that Friday’s nationwide ground stop ordered by the FAA was related to work replacing outdated copper wire with a fiber optic line at a “remote FAA facility.” The secretary said that this was “routine maintenance,” rather than the result of a major modernization effort. He told reporters that it was “such an old wire that it was being discontinued, meaning that line was going to get shut down,” necessitating the upgrade.

What wasn’t clear, according to Secretary Duffy, was the root cause of the problem. He said that it could have been faulty hardware, a misconfigured router, or “incompetence” on the part of contractor L3Harris. Regardless, what followed was the newly installed router “flooding” other routers in the Air Traffic Control system.

Duffy said that there were “over 1,000 connection attempts every 4 to 5 seconds,” causing disruption to radar feeds and communication with planes.

Secretary Duffy also took the opportunity to call on additional funding from Congress for modernizing the Air Traffic Control system , and to tout the work the FAA has done so far. “We are building, we are building safely, but we are building fast,” he said, but said that Congress had only given him a “partial payment” to complete the necessary work.
