US halts flights at busy East Coast airports, says fiber line cut

The US Federal Aviation Administration (FAA) halted some flights at busy East Coast airports due to communication issues caused by a cut fiber line. The FAA announced the disruption on September 21, 2023, stating that it was affecting several airports in the New York City area. The affected airports included John F. Kennedy International Airport (JFK), Newark Liberty International Airport (EWR), and LaGuardia Airport (LGA). The FAA said that the issue was caused by a cut fiber line, which disrupted communication between air traffic control systems and planes. The agency worked to restore communication and resume flights as quickly as possible. It is unclear what caused the cut fiber line, and the FAA did not provide further details. The disruption caused delays and cancellations for several flights, but the FAA did not provide an exact number. The agency apologized for the inconvenience caused and assured that it was working to resolve the issue as soon as possible.
