(AP) The websites for some major U.S. airports appear to be recovering after having gone offline.

Officials said flights were not affected.

A spokesman for Atlanta’s Hartsfield-Jackson International Airport said Monday that the external website was down earlier in the day. He said IT and security people are investigating. It’s a similar story across the country, as parts of the website for Los Angeles International Airport also were disrupted.

A spokeswoman said LAX notified the FBI and the Transportation Security Administration.

Last week, hackers claimed responsibility for cyberattacks against state government websites across the country.
