Failure during modernization of US air traffic control halted flights for more than four hours

TechnologyInternationalInfobaeNov 14, 2026, 9:04 AMAI summary

A telecommunications failure paralyzed US airspace for more than four hours: air traffic control switches and routers became saturated during the installation of new technology and distributed inconsistent data among the 22 operating centers. The FAA ordered the ground stop and lifted it after confirming system stability. FlightAware recorded more than 9,000 delayed flights and more than 7,000 cancellations on Friday, and by Saturday cancellations exceeded 3,000. The government acknowledged there will be more disruptions during the modernization.

The failure originated in switches and routers of the old system, which could not handle the data volume transmitted by the new digital systems, according to Transportation Secretary Sean Duffy.
It was the FAA's second nationwide ground stop since September 11, 2001; the previous one occurred in January 2023 due to a failure in the pilot notification system.
Congress approved USD 12.5 billion in 2025 to modernize the system and Duffy requested another USD 50 billion the same day as the ground stop.

SimRosario: a young man recreated Rosario with AI in the style of SimCity
Agustín Abraham, a young man from Rosario, created SimRosario, a platform that turns real aerial photographs of the city into an illustrated map with the aesthetic of the SimCity video game. He started from oblique Google Maps images taken between 2012 and 2013 and trained AI models, with manual review, to illustrate 2,308 sectors. The result is an image of about 48,000 by 52,000 pixels, split into tiles so it can be browsed from a computer or phone.
