Overview
- The FAA ordered a nationwide halt on departures on Friday after controllers reported intermittent communications and radar visibility across multiple air‑traffic centers.
- The shutdown lasted several hours but reopened Friday evening; carriers and airports reported more than 16,000 cancellations across Friday and Saturday with thousands more delays continuing into Sunday.
- Investigators describe a technical chain in which replacing copper lines with fiber coincided with a router failure that propagated link instability to communications and radar systems.
- Federal officials including the FBI say there is no evidence so far of a cyberattack, and national security leaders have emphasized the outage appeared to be a technical failure.
- The incident has sharpened a funding fight in Washington, with Transportation Secretary Sean Duffy seeking roughly $50 billion for FAA modernization while the White House has requested $30.1 billion, and officials warn recovery could take days as aircraft and crews are repositioned ahead of Thanksgiving travel.
