A sudden power outage caused by a fire in an underground electrical facility brought the airport to a standstill. Georgia Power said on its Twitter page that "Power has been restored on all concourses. Passengers at the airport were left in the dark when the lights went out at around 1 p.m. The utility said that there are "many redundant systems in place" to ensure the power supply to the airport and that such outages at the airport "are very rare." Hartsfield-Jackson, which serves 104 million passengers a year, is the world's busiest airport, a distinction it has held since 1998.
