Thousands of flights in the U.S.A. are grounded Wednesday morning after a computer outage at the Federal Aviation Administration.

The Associated Press reports that the FAA had a failure in its Notice to Air Missions System.

"NOTAMs used to be available through a hotline but that was phased out with the internet. The alerts span from mundane information about construction at airports to urgent flight restrictions or broken equipment," the AP reports. "There is a potential for widespread disruption because of the outage. All aircraft are required to route through the system, including commercial and military flights."

Just before 6:30 a.m. CST, the FAA tweeted that it is grounding all domestic departures in the U.S.A. until 8 a.m. CST "to allow the agency to validate the integrity of flight and safety information."

As of 6:30 a.m. the Winnipeg Airports Authority did not show any disruptions to flights headed south of the border.
