FAA lifts nationwide ground stop after air traffic control equipment failure
The FAA halted all US flights for hours starting the afternoon of November 13 after aging air traffic control routers using legacy TDM telecom technology became overloaded with data and began sending inconsistent information. The stop, lifted at 8:15PM Eastern, led to canceled flights, in-air diversions and stranded passengers, and was only the third such nationwide stoppage this century.

Transportation Secretary Sean Duffy attributed the failure to outdated infrastructure and said Congress has not funded the roughly $30 billion he says is needed beyond the $12.5 billion already allocated, suggesting further disruptions could recur without additional funding. Homeland Security Secretary Markwayne Mullin said there was no evidence of a cyberattack but that investigators were not ruling it out, leaving some uncertainty about the root cause.
- Nationwide ground stop began afternoon of Nov 13 and was lifted at 8:15PM Eastern.
- Cause traced to overloaded legacy TDM routers in parts of the air traffic control system not yet upgraded.
- Officials say no evidence of cyberattack so far, though Homeland Security has not ruled it out.
