At a White House press conference, US Transportation Secretary Sean Duffy provided a preliminary explanation for the malfunction. According to him, "the switches and routers were actually flooded with data, and they collapsed." He clarified that during the stoppage of the flights there was no complete failure of the communication systems or the radar, and defined the incident as a malfunction of an outdated network. "It will take time for us to return to full capacity," he said.
