US officials have officially lifted the nationwide airport ground stop that caused significant travel disruptions earlier today. Authorities clarified that the shutdown was not the result of a cyberattack or the recent global Microsoft software issues, but rather a direct consequence of aging infrastructure. The system failure occurred when legacy hardware—specifically switches and routers—became overloaded with data and crashed, forcing a pause in air traffic.

While the airspace has been reopened, officials warned that flight schedules will recover gradually. The incident has intensified calls for legislative action, as the White House and transportation authorities have been urging Congress to approve a $30 billion investment to modernize the nation's air traffic control systems. Despite the technical breakdown, officials emphasized that the national airspace remains safe for travel and maintained that there is no evidence of malicious interference, though security agencies continue to monitor the situation as a standard precaution.
