Sec. Sean Duffy on FAA Ground Stop: Routers 'Got Overloaded with Data'
A ground stop across the U.S. airports prompted Transportation Secretary Sean Duffy to attribute the disruption to an aging air traffic control system, whose routers reportedly produced data inconsistencies after being overloaded. He described the system as outdated and urged Congress to fund a full modernization, reiterating bipartisan support for a multi-billion dollar upgrade. The briefing, conducted with DHS Secretary Markwayne Mullin, also noted there was no evidence of a hostile attack. The episode highlighted recurring reliability issues and ongoing calls for a comprehensive, state-of-the-art ATC rebuild. The administration aims to secure substantial funding to prevent future outages and restore confidence in national air travel operations.

Duffy explained at a press conference with DHS Secretary Markwayne Mullin that the FAA ground stop occurred because routers became overloaded with data, causing inconsistencies in the information they provided.
He characterized the U.S. air traffic control system as incredibly old, linking the outage to long-standing concerns about funding for a full, modern rebuild rather than a patchwork fix.
Duffy noted that President Trump has been advocating for bipartisan Congressional action to supply resources for a comprehensive ATC modernization, citing a need for serious investment rather than minor repairs.
He referenced past outages, including incidents in Newark about a year and a half earlier, to emphasize that the problem is ongoing rather than a one-off event.
Duffy indicated discussions with Trump about significant funding, mentioning amounts in the realm of $30 billion to $50 billion for the modernization effort, and criticized the current equipment as having issues like leaky roofs and malfunctioning air conditioning in control facilities.
Mullin stated there was no indication of a nefarious attack contributing to the ground stop, reinforcing that the incident appeared to be technical and related to aging infrastructure.
