The skies stopped: aging infrastructure halted U.S. civilian aviation amid a massive failure. The Federal Aviation Administration (FAA) imposed a nationwide ban on all U.S. airports. The cause was a fault in the communication infrastructure that links air traffic control centers. The restrictions were imposed on the government at 15:54, or almost midnight Moscow time, and lasted more than four hours. All 22 FAA regional air traffic control centers were affected. Aircraft in the air continued to fly and land, but new flights were prohibited. The U.S. Secretary of Transportation explained the incident as router overload and equipment malfunctions. According to him, the new equipment added extra load to the old infrastructure. There were no signs of a cyber attack. After the restrictions were lifted, air traffic activity gradually resumed, but the consequences of the failure continued to affect the schedule. According to FlightAware, thousands of flights were canceled and additional delays occurred. The Amtrak rail operator also had booking issues amid a sharp rise in travel demand, although train traffic did not stop. This is the second failure in the country since January 2023, when the NOAM pilot readiness system failed. A country with one of the largest airline networks in the world again demonstrated how vulnerable its transportation infrastructure is. To halt flights across the country, no military attack or large-scale cyber attack was needed – just problems with its communication system.
