The websites for some major U.S. airports went down early Monday in an apparent coordinated denial-of-service attack, although officials said flights were not affected.

The attacks followed a call by a shadowy group of pro-Russian hackers that calls itself Killnet for coordinated denial-of-service attacks on the targets. The group published a target list on its Telegram channel.

“We noticed this morning that the external website was down, and our IT and security people are in the process of investigating,” said Andrew Gobeil, a spokesman for Atlanta’s Hartsfield-Jackson International Airport. “There has been no impact on operations.”
