United Airlines flights, which were temporarily grounded nationwide Wednesday morning, are taking off again from Hartsfield-Jackson Atlanta International Airport.

“United’s system has been restored and they are now processing passengers,” airport spokesman Reese McCranie told The Atlanta Journal-Constitution in an emailed statement just after 10:30 a.m.

According to the Federal Aviation Administration, the ground stop, which affected United Airlines and its sub carriers only, was due to "automation issues."

It came one month after United flights were grounded, also due to unspecified automation issues. The airline cited faulty flight information in the airline's dispatch system, TIME reported.

Hartsfield has an average of 26 daily United flights with about 2,300 seats, he said. Not every flight is full.

“The impact,” McCranie said, “has been minimal.”
