The nationwide shutdown occurred when a router flooded traffic control networks during a contractor's routine transition from copper wiring to fiber optics. Federal Aviation Administration head Bryan Bedford and other officials confirmed there is no evidence of cyber-attacks or nefarious interference, focusing the investigation instead on faulty equipment or contractor errors. The resulting flight snarls are expected to linger for several days, leaving thousands of passengers stranded across the country. Meanwhile, the administration is using the incident to press Congress to approve billions in infrastructure modernization.

A nationwide US ground stop that caused thousands of flight cancellations was caused by an issue following a copper wire upgrade, Transport Secretary Sean Duffy said.
Duffy told a news conference that the government was trying to find out whether the problem was caused by "incompetence" on the part of the company doing the upgrades, or faulty equipment.
The US government does not believe it was as a result of a cyber-attack, although an investigation is still under way, Duffy said.
Friday's suspension was the longest such incident since the 11 September 2001 attacks on the US and the disruption is expected to last for days.

Maintenance was being carried out to switch from copper wire to fibre by a contractor called L3Harris, a technology provider company, Duffy said.
The US has "an incredibly old telecommunications system", he added.
"It was such an old wire that it was being discontinued," he said.
Routine infrastructure maintenance at a remote facility disrupted radar feeds and aircraft communications, triggering a nationwide halt that grounded thousands of flights on Friday. Upgrades were required to transition to fiber optics because the legacy infrastructure faced an imminent shutdown. Transportation officials are now investigating technical failures and contractor performance while pressing federal lawmakers for additional modernization resources.
Investigators are looking into technical upgrades after an infrastructure transition caused disruptions across the Federal Aviation Administration network late last week. Officials suspect hardware defects introduced during telecom modernization efforts triggered the technical breakdown. The incident raises fresh scrutiny over private vendors managing critical telecommunications systems for government aviation operations.
