Air traffic at more than two dozen major airports across the United States was delayed this afternoon due to a communications network problem, according to the Federal Aviation Administration's website.
The Department of Homeland Security declined to comment, referring calls to the FAA.
CNN said air safety was not affected and the FAA has not lost contact with any of the 5,825 flights in the air.
The computer glitch occurred at an FAA facility south of Atlanta, CNN reported.
