Amtrak Crew Cuts Backup Fiber Cable After FAA Circuit Fails

A primary telecommunications circuit failed at the FAA’s Philadelphia TRACON. When the system switched to backup, the backup fiber was found cut by an Amtrak construction crew in New Jersey; Verizon confirmed its cable beside an Amtrak line was cut. The FAA halted incoming flights at Philadelphia, Newark, Teterboro, JFK, LaGuardia and Boston. FlightAware estimated more than 5,600 US delays or cancellations, including 1,200 at the New York-area airports, with more than 100 diversions. Boston’s spillover stop was lifted; LaGuardia and Philadelphia briefly resumed before Philadelphia halted again; Reagan National paused over an hour for volume. Bryan Bedford said: “When it went to flip into the backup, we discovered that the backup fiber had a break, and that fiber break is probably 13 hours to repair. It's massive, I'm told. Meanwhile, we've got the new circuit ready to install now.” Sean Duffy said “This is unacceptable in America” and sought another $17.5 billion beyond last year’s $12.5 billion. The disruption hit as 130 world leaders arrived for the UN General Assembly. No material fact disputes appear across outlets; full resumption waited on safe airspace and repairs.
