The Federal Aviation Administration issued a nationwide ground stop for all airports in the U.S. on Friday afternoon, citing a communication issue impacting air traffic control centers.

U.S. Department of Transportation Secretary Sean Duffy announced the stoppage at about 1:15 p.m. and said that FAA technicians were investigating the issue.

FAA officials on social media characterized the issue as “a temporary telecommunications outage” and said all flights have been accounted for, while international flights “will be handled on a case by case basis.”

San Francisco International Airport officials said as of 3 p.m. that Pacific-bound flights were cleared to take off from SFO, including destinations in Hawaii and Asia.

Airport officials advised people to check with their airline for their latest flight information.
