Al Jazeera's live blog covers the Federal Aviation Administration's nationwide ground stop, issued at 20:54 GMT on 13 November 2026 after a telecommunications outage hit all 22 air traffic control centres, with airborne aircraft told to hold and flights still grounded more than two hours later. Officials, including Homeland Security Secretary Markwayne Mullin, said there was no indication of an attack, while Bloomberg reported the FBI suspects a software update may be to blame, and nearly 7,000 flights had been delayed or cancelled.
