UPDATE: January 11, 2023, 2:55 p.m. CET Departures resume after the FAA successfully restores its NOTAM system. “Normal air traffic operations are gradually resuming across the United States following an overnight outage of the Air Mission Advisory System that provides safety information to flight crews. The ground shutdown has been lifted,” said the FAA in a tweet. The agency says it is still investigating the cause of the outage.
Flight departures across the United States have been suspended as the Federal Aviation Administration (FAA) attempts to recover from a system outage.
According to the FAA, the issue involves the agency’s Notice to Air Missions (NOTAM) system, which became unavailable early Wednesday.
NOTAM sends essential messages to personnel involved in flight operations, such as the abnormal state of a component of the national airspace system.
“The FAA is working to restore its Air Mission Advisory system. We are performing final validation checks and reloading the system now,” the FAA said in a tweet Wednesday. The agency went on to say that “while some functions begin to come back online, operations of the national airspace system remain limited.”

In a third tweet, the FAA said it was “still working to fully restore the Air Mission Advisory system after an outage.”
“The FAA has directed airlines to suspend all domestic departures until 9 a.m. Eastern Time to allow the agency to validate the integrity of flight and safety information,” said the FAA.
The cause of the outage is currently unknown. According to CNN, President Joe Biden ordered a Department of Transportation (DOT) investigation into the outage. According to White House press secretary Karine Jean-Pierre, there is “no evidence of a cyberattack at this stage”.
