Airports across the northeastern U.S. resumed operations Monday after a telecommunications failure at a Federal Aviation Administration radar facility disrupted flights across the region for hours.
The outage affected major airports in the New York and Philadelphia areas, including Newark Liberty, Teterboro, Philadelphia International, LaGuardia and John F. Kennedy International. While communications have been restored, airlines continued working through delays and cancellations caused by the disruption.
The FAA said the primary telecommunications circuit at its Philadelphia Terminal Radar Approach Control Facility (TRACON) failed earlier Monday. The facility typically handles air traffic across a large area around Philadelphia and New York, managing flights in and around some of the region’s busiest airports.

The situation was further complicated when the backup fiber system was also found to be unavailable because of a break in the line.
A fiber optic line in New Jersey that was supposed to serve as a backup was accidentally damaged during construction work near an Amtrak rail line, affecting Verizon communications lines. Verizon said contractors working in the area dug up and cut the cable and that the damage was not caused by the telecommunications company. The company added that its cables had been properly placed.
Newark was among the airports hardest hit by the disruption. According to flight-tracking data, about 107 flights had been diverted from Newark to 34 different airports by 5:30 p.m. local time. Washington Dulles International Airport received 19 of the diverted flights. More than 300 flights had been canceled as of Monday evening.
The timing of the incident also created additional pressure for New York. The city is hosting the 81st United Nations General Assembly this week, bringing leaders and diplomats from around the world. The disruption affected some high-profile travelers, including Canadian Prime Minister Mark Carney. His office said his arrival was delayed, causing him to miss a scheduled meeting.

The incident has raised renewed questions about the country’s air traffic control infrastructure. FAA Administrator Bryan Bedford said the agency aims to replace the existing system with a modern federal enterprise network. He said, “This is why we’re asking for budget to replace all of this stuff … We’re pulling copper up and putting fiber down, but it’s the same data architecture that we’ve had for 50 years.”
“This incident underscores the need for additional funding to modernize aging infrastructure and prevent disruptions like this in the future,” Transportation Secretary Sean Duffy wrote in an X post. He added, “This is not a new problem. It’s an old system that we were stuck working with.”
The Philadelphia TRACON facility has faced similar problems in the past. In 2025, a brief outage contributed to flight disruptions around Newark.
Duffy announced plans last year for a “brand new air traffic control system” by 2028, making modernization a key priority of his tenure. He said more than 4,600 sites would receive new high-speed network connections, replacing outdated telecommunications lines with fiber, wireless and satellite links by 2028.
The latest incident has renewed calls to strengthen the communications infrastructure and ensure reliable backup systems are in place to prevent similar disruptions in the future.
