The FAA issued the ground stop around 3:36 p.m. ET after overloaded routers disrupted air traffic control during routine maintenance to switch from copper wiring to fiber optics. Transportation Secretary Sean Duffy blamed decades-old analog equipment failing under modern loads, though safety measures ensured all airborne planes landed safely and the airspace reopened by 8:15 p.m. ET. The incident, only the second nationwide halt since 9/11, prompted Duffy to push Congress for more funding to modernize systems, amid political finger-pointing from Gov. Gavin Newsom and ongoing recovery with thousands of cancellations.
