GoKawiilFAA 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.
