A computer failure causes the suspension of thousands of flights in the United States

Flights across the United States were affected Wednesday morning after the Federal Aviation Administration (FAA) suffered a massive computer outage.

All flights in the United States were grounded after the incident, a source familiar with the situation told NBC News, the sister network of Noticias Telemundo.

The FAA indicated in a notice on its website that its Notification of Air Missions (NOTAM) system had "failed" on Wednesday morning.

A NOTAM is a notice containing essential information for workers involved in flight operations.

"The technicians are working to restore the system and there is no estimate for the restoration of service at this time," they communicated.

About 760 flights in, in and out of the US were delayed as of 6:30 a.m. Wednesday, according to the FlightAware flight tracking website.

About 90 flights were listed as cancelled.

"Operations throughout the National Airspace System have been affected," the FAA detailed in a statement.

“The FAA is working to restore its Air Mission Notification System.

We are performing final validation checks and repopulating the system now."

“We will provide frequent updates as we progress,” they added.

“An FAA system outage is causing ground stops at AUS and other airports across the country,” Austin-Bergstrom International Airport said on Twitter.

"Arriving and departing passengers can expect delays this morning and throughout the day," he said, adding: "Please keep in touch with your airline & check your flight status before heading to AUS."
