According to Jin10, U.S. Homeland Security Secretary Malin and Transportation Secretary Sean Duffy said at a White House press conference on November 13 that a telecommunications failure caused the nationwide flight groundings and that the public had no need to panic. Duffy said there was no complete outage of communications or radar systems while the ground stop was in effect. He attributed the failure to problems with an old network system and urged Congress to provide $50 billion in emergency funding to upgrade air traffic control systems. Malin said the incident was unrelated to Microsoft’s earlier service application outage, that there was no evidence of a cyberattack or AI intervention, and that response efforts were ongoing. He said outdated systems and data overload posed national security risks.
