Just under a third of the flights at Cincinnati/Northern Kentucky International Airport were delayed or canceled Wednesday after the Federal Aviation Administration computer glitch.
The glitch prompted the FAA to order a nationwide pause on departures, known as a ground stop, for about 90 minutes Wednesday morning.
The ground stop order was issued due to an outage of the Notice to Air Mission system, or NOTAM, which is key to communicating safety information to flight personnel.
Though the order was lifted shortly before 9 a.m., there was a cascading effect on flight operations across the country with about 10,700 flights delayed and almost 3,000 canceled over the day.

As heavy rain and storms move into the region Thursday morning, nine delays and zero cancelations had been reported at CVG by FlightAware out of the 364 scheduled arrivals and departures.

The FAA has not yet identified a specific cause of the issue, but experts told USA Today that the U.S. air traffic control system often relies on outdated technology to keep things moving, and it's likely that a computer glitch of some kind was responsible.
The FAA said it's investigating the problem but hasn't issued an official cause yet.
