Hartsfield-Jackson International Airport turned its wi-fi back on late Monday afternoon, more than a week after it turned it off due to a cyber attack on the city of Atlanta.

The world’s busiest airport switched on its free wi-fi at around 5:30 p.m. Monday.

The airport took down the wireless Internet service more than 10 days ago, with spokesman Reese McCranie saying at the time: "While we aren't directly affected by the cyberattack, we are being abundantly cautious and have taken these systems offline."
