The Federal Aviation Administration (FAA) issued a nationwide ground stop on Friday afternoon, November 13, 2026, after a temporary telecommunications outage disrupted communications at multiple regional air traffic control centers. The order, which remains in effect until at least 11:00 p.m. EST, reflects the agency’s commitment to safety and its “abundance of caution” in handling the situation.
What triggered the grounding?
The FAA described the event as a “temporary telecommunications outage” that required all flights to be halted while the system was assessed. An unconfirmed report from CBS correspondent Olivia Rinaldi linked the outage to a reboot of the private communications network that connects America’s air traffic control system, a network managed by L3Harris Technologies.
Immediate impact on travelers
Within two hours of the grounding order, FlightAware reported more than 1,100 flight cancellations and 11,000 delayed flights across the country. International flights are being evaluated on a case‑by‑case basis, and the FAA emphasized that every flight has been accounted for.
Government response
U.S. Department of Homeland Security Secretary Markwayne Mullin cautioned against speculation, stating that the problem appears to be a “telecommunications outage” with no initial evidence of a “nefarious attack against us.” He added, “There is no reason to be concerned about your loved ones if they’re flying… the safety of everybody that is flying is our top priority, and we are assured that everyone in the air is safe. We’ll get you on the ground as soon as possible.” By placing the administration’s reassurance near the top of the story, readers see the clear, calm response from federal officials.
Context and broader concerns
The grounding follows a similar nationwide event on January 11, 2023, when the FAA’s Notice to Air Missions (NOTAM) computer system crashed. Some reports mistakenly claimed the November 2026 stop was the first since the September 11, 2001 attacks, but the 2023 incident demonstrates that the FAA has previously taken decisive action to protect the traveling public.
Additionally, the FAA grounding occurred one day after a global outage that took most Microsoft services offline. Both Microsoft and the federal government have stated that the two incidents are unrelated, underscoring that the aviation issue stems from its own communications infrastructure rather than a broader cyber‑attack.
Looking ahead
The FAA continues to monitor the situation and will provide updates as the telecommunications systems are restored. Travelers are encouraged to check with airlines for the latest flight status and to remain patient as the agency works to resume normal operations safely.
While the outage raised concerns about the vulnerability of critical American infrastructure, the swift grounding and clear communication from the FAA and DHS illustrate a proactive approach to safeguarding the nation’s air travel system.
