FAA lifts nationwide ground stop after overloaded routers disrupt air traffic communications
The FAA halted flight departures nationwide after a communications failure at air traffic control centers, causing major airport disruption and the longest nationwide shutdown since the Sept. 11, 2001, attacks. The ground stop was lifted after officials attributed instability beginning at 3:36 p.m. to overloaded, aging equipment; they said there was no indication of an attack.
