US Transportation Secretary Sean Duffy said the nationwide aviation shutdown in the United States, which resulted in thousands of flight cancellations, was caused by a problem following work to upgrade the copper wiring. At a press conference, Duffy said the US government was trying to determine whether the problem had been caused by “incompetence” on the part of the company carrying out the upgrade or by faulty equipment. The US government does not believe the incident resulted from a cyberattack, although the investigation is still ongoing, Duffy said. According to him, maintenance work to replace copper wiring with fiber-optic cable was carried out by a contractor called L3Harris, a technology services provider.
