The Federal Aviation Administration ordered the nationwide ground stop on Friday afternoon after updated routers flooded the air traffic control system with roughly 1,000 connection attempts every few seconds. Systems stabilized once the remote work locations, believed to be in Arkansas and Texas, were isolated. The incident disrupted 17 of the agency's 22 en route centers, prompting Transportation Secretary Sean Duffy to call for $50 billion to overhaul the nation's aging aviation infrastructure.
