Following a March 22 cyberattack on the City of Atlanta government, Hartsfield-Jackson Atlanta International Airport (ATL) has temporarily shut down its Wi-Fi system, leaving the airport’s approximately 275,000 daily passengers and 63,000 employees scrambling for internet connectivity.

Reportedly, the Atlanta city government experienced a ransomware cyberattack the morning of March 22 impacting multiple internal applications; city employees were advised to not use their computers.

The airport announced via Twitter Thursday afternoon that its Wi-Fi system was temporarily down, and that the airport was working to fix the situation.

ATL released an update March 23 on both Twitter and its website affirming continued “internet difficulties … ATL’s Wi-Fi, along with security line wait times and flight information may not be accurate,” advising customers to check with their airlines.

According to the Atlanta Journal-Constitution an ATL spokesperson said a timeline for restoration of the airport’s Wi-Fi was unclear. The spokesperson said the airport had not been directly affected by the cyberattack, but had decided to take its systems offline out of an abundance of caution.
