2023 FAA system outage - Wikipedia
A Wikipedia article covers the January 11, 2023 FAA NOTAM system outage, which forced the first nationwide ground stop since September 11, 2001, grounding U.S. flights for nearly 12 hours and delaying more than 10,000 flights. Investigators attributed the failure to a contractor's mistaken file deletion, the FAA said there was no evidence of a cyberattack, and President Biden ordered an investigation.
