Transport Secretary Sean Duffy said the ground stop was caused by an issue following the upgrade of a copper wire, which led to thousands of aircraft cancellations across the US. We’re trying to determine whether it’s incompetence on the part of the company that’s doing the upgrades, or whether it’s faulty equipment,” Duffy said reporters during a news conference.
Duffy said an investigation is ongoing but the US government does not believe it was as the consequence of a cyber-attack. The stoppage on Friday was the longest such episode since the September 11, 2001 attacks on the US and the disruption is likely to linger for days.
A router, which was being worked on, had begun to flood other air traffic control systems and caused communication issues with planes, which forced the government to shut down the airspace for safety concerns, the transport secretary said. Bryan Bedford, who heads the Federal Aviation Administration (FAA), told the same news conference: “We see zero evidence of anything nefarious, and zero evidence of anything AI-related.
