The company says construction contractors working near an Amtrak rail line dug it up, that Verizon's facilities were fully functional until that happened, and that the carrier bears no responsibility for the incident. Technicians are on site, and the company says it is working to repair the damaged cable and restore connectivity.

FAA Administrator Bryan Bedford told reporters an older circuit serving Philadelphia TRACON failed this morning. Controllers tried to flip to the backup fiber the agency had installed as part of its modernization push, and the backup was already dead. The agency did not know the fiber was cut until the primary circuit went down, Bedford said. The damaged stretch is roughly 600 feet between New Brunswick and Newark. Repairing that line, he said, could take about 13 hours. "It's massive, I'm told."

Transportation Secretary Sean Duffy put it more bluntly: an Amtrak construction crew cut into the fiber and forced the FAA to pause Northeast traffic.

By mid-afternoon LaGuardia had resumed in some form, and Philadelphia and JFK were being walked back from full ground stops toward delay programs. Newark and Teterboro were still the problem children. That is the airspace Philadelphia TRACON was handed in 2024, the same facility that had radio-frequency trouble last August and a string of radar and comms failures through 2025.

The FAA is trying to stand up a replacement circuit rather than wait out a 13-hour splice. Until the data is flowing again, inbound traffic into the remaining restricted fields stays on the ground at origin, which is still a ground stop, still the most restrictive tool the agency has. World leaders are landing in New York this week for the UN General Assembly.

The FAA has issued ground-stop orders to arrivals into every major New York-area airport: JFK, LaGuardia, and Newark. Teterboro, Westchester, and Philadelphia are in the same pile. Official reason: equipment outage.

What happened

The first restrictions hit Newark, Teterboro, and Philadelphia after problems with radio frequencies at Philadelphia TRACON, the terminal radar facility that handles arrivals and departures in that airspace. The FAA later added JFK, LaGuardia, and Westchester.

The agency has not publicly detailed which systems failed, how long repairs will take, or whether New York TRACON (N90) is separately affected. That lack of specifics is why the disruption is being described as an "unknown equipment issue."
