Officials at Bristol Airport in the U.K. blamed a cyber attack on the airport’s IT system. Flight information screens were taken offline on Friday as a precautionary measure. Flights were unaffected and information was posted on whiteboards and announced over the public speaker system over the weekend. At roughly 4:30 a.m. local time on Sunday, Bristol Airport tweeted a photo of the restored live flight information on the digital screens. The airport tweeted about the long downtime on a cautious approach as IT rebuilt affected systems.”]
