The UK’s Bristol Airport was the target of a cyberattack that attempted to infect its system with ransomware. To contain the incident, the digital screens that provide key information, like arrival and departure times and where to pick up luggage, were taken offline.

The BBC reports, “Spokesman James Gore said: ‘We believe there was an online attempt to target part of our administrative systems and that required us to take a number of applications offline as a precautionary measure, including the one that provides our data for flight information screens.'”

The incident began Friday morning. By Sunday morning, the information screens were back up. Until then, though, the airport relied on old-school manual processes, using whiteboards and markers to post information.

ZDNet notes that this is not the first airport to be impacted by a cyberattack. When the city of Atlanta was hit with a ransomware attack in March, Hartsfield-Jackson Atlanta International Airport took its internal Wi-Fi network offline as a security precaution.

According to the Bristol Airport spokesman, no security or safety systems were affected.
