Newshot Has the “culprit” behind the nationwide U.S. flight grounding been found? FAA investigation points to a 20-year-old router
IT之家 November 14 news: CBS News transportation correspondent 克里斯 Van 克利夫 posted on X, citing a senior U.S. government official, that the faulty equipment that caused the nationwide ground stop has been identified and isolated.
克利夫, citing the official, said the Federal Aviation Administration (FAA) believes the failure involved only one “specific model” of 20-year-old router. “The (system) was basically overwhelmed by load, though the specific cause is not yet clear.”
Preliminary information shows that after the router became overloaded, it began transmitting out-of-sync data, causing noise on air traffic controllers’ voice communication lines and possibly causing displays to flicker or go black, similar to a failure that occurred at Newark Liberty International Airport in 2025.
According to an earlier IT之家 report, on the 14th local time, data from flight tracking website FlightAware showed that after a communications failure in the air traffic control system on the 13th grounded all aircraft across the U.S., more than 3,300 flights within the United States and to and from the United States had been canceled on the 14th.
