TechWork to replace old copper wire led to the FAA’s ground stop

Transportation Secretary Sean Duffy said the FAA’s nationwide ground stop on Friday was linked to replacing outdated copper wire with fiber at a remote facility. A newly installed router then flooded other air traffic control routers with connection attempts, disrupting radar feeds and communications with planes. The cause remains unclear; Duffy cited possible faulty hardware, a misconfigured router, or contractor L3Harris’s incompetence. He also urged Congress to fund air traffic control modernization.
