FAA Orders First Nationwide Ground Stop Since 2023 After Comms Failure Hits 22 Centers

The Federal Aviation Administration halted every flight in US airspace on the afternoon of Nov. 13 after a communications failure struck all 22 regional air traffic control centers — the first nationwide ground stop since January 2023, and only the third since the Sept. 11, 2001 attacks.

The FAA's own notice described "extraordinary circumstances and for reasons of safety." Transportation Secretary Sean Duffy confirmed the disruption ran across the full network of 22 centers that direct aircraft flying between airports, with FAA technicians deployed to investigate. Homeland Security Secretary Markwayne Mullin said there was no indication of a nefarious act behind the failure.

That reassurance, notably, is a negative finding — an absence of evidence at an early stage of the investigation, not a conclusion about what actually broke.

How severe was the disruption?

By the rarest of measures: this was the first event of its kind in nearly three years. The January 2023 stoppage followed the malfunction of a key FAA computer system, and the only prior nationwide ground stop came after 9/11. Aviation safety expert Steve Arroyo, a former United Airlines pilot, said the Nov. 13 failure resembled a regional communications outage in September that snarled hundreds of flights across the Northeast — except this time it scaled nationwide.

"If you don't have that ability, whether it's because the old wires that they have are just run down or for whatever reason, you've got to stop airplanes on the ground," Arroyo said. "And not put them in the air where you're going to risk not being able to communicate with them."

One distinction mattered operationally: unlike the post-9/11 order, aircraft were not told to land immediately. Arroyo said pilots most likely retained contact with ground controllers at airports, meaning airborne traffic was not cut off from all guidance.

Why aging infrastructure sits at the center of this story

The outage lands in the middle of a multibillion-dollar technology overhaul. Congress approved $12.5 billion for the modernization last year. Since then, crews have replaced miles of old copper wiring with fiber optic lines and have gradually swapped out aging radio systems at airports across the country.

That work is unfinished — and the price tag is climbing. Duffy has said another $30 billion is needed to complete the program, and the White House has begun lobbying Congress to approve it. For context, that additional request is roughly 2.4 times the entire sum Congress has already committed.

Arroyo pointed to the possibility that the failure is linked to the outdated technology controllers still rely on — the same systems the overhaul is meant to retire. The FAA has not confirmed a cause; technicians were still investigating at the time of reporting.

What this means for air cargo and shippers

A nationwide ground stop of this scope halts belly cargo and freighter operations alike, forcing integrators and freight forwarders to rebuild schedules across every US gateway at once. A single-event disruption across 22 en-route centers differs sharply from a weather or regional outage, which can be rerouted around; there was no unaffected lane to shift capacity into.

The September Northeast outage, which disrupted hundreds of flights, offers a benchmark for recovery drag: even short-duration stops produce cascading delays and repositioning costs over subsequent days.

Whether Nov. 13's event accelerates congressional action on the $30 billion request — or hardens resistance to it — will depend heavily on what the FAA's technicians find.
