A cut cable disrupted hundreds of flights across the US
Hundreds of U.S. flights were delayed or cancelled after a Verizon fiber cable used for air traffic control was severed during construction work in New Jersey. The outage triggered ground stops at the region's major airports and prompted finger-pointing between carriers and contractors over who cut the line.
Why It Matters
The incident disrupted airport operations across the Northeast, highlighting the dependence of air-traffic systems on terrestrial telecom infrastructure and the cascading effects a single infrastructure failure can have on national travel. It also sparked conflicting claims of responsibility among transportation agencies and contractors.
Key Facts
- Scope of disruption: Hundreds of flights were cancelled or delayed; FlightAware reported over 1,000 cancelled flights in the U.S. that day.
- How problem was discovered: FAA Administrator Bryan Bedford said a circuit failure led to discovery of the severed fiber cable.
- Airports affected: The outage prompted ground stops at all three major New York City airports and affected airports across the Northeast.
- Verizon statement: Verizon told CNBC it bore 'no responsibility' and blamed 'construction contractors working in the area' who 'dug up and cut our cable.'
- Dispute over who cut the line: U.S. Transportation Secretary Sean Duffy said an Amtrak crew accidentally cut the line; Amtrak responded that the incident occurred on New Jersey Transit property and involved a New Jersey Transit contractor.
A severed Verizon fiber cable used for air-traffic-control communications caused major travel disruptions across the U.S. Northeast when construction crews in New Jersey accidentally cut the line. The fault was detected after a circuit failure, according to FAA Administrator Bryan Bedford, and the outage led to ground stops at the three main New York City airports and delays at other regional hubs. Verizon issued a statement to CNBC saying the company was not responsible and blamed construction contractors who 'dug up and cut our cable.' The incident quickly produced conflicting accounts about which crew was at fault. U.S. Transportation Secretary Sean Duffy said an Amtrak crew had accidentally cut the line, while an Amtrak spokesperson told NBC4 that the work took place on New Jersey Transit property and involved a New Jersey Transit contractor. By Monday evening, Duffy said the telecom lines had been repaired and that airport operations in the Northeast were resuming, though he warned it would take time to clear the backlog of delayed and cancelled flights. FlightAware recorded more than 1,000 cancelled flights across the United States on the day of the outage. The disruption underscores how terrestrial fiber infrastructure supports air-traffic control systems and how damage to those networks can cascade into large-scale travel interruptions. Authorities and the involved transit organizations provided differing accounts as investigators and operators worked to restore connectivity and clear disrupted flight operations.
