South Koreans refuse to comment on rumours Russia was behind the action as revenge for doping ban
Winter Olympics officials have confirmed the games were hit by a cyber-attack during the opening ceremony – but have refused to confirm rumours in Pyeongchang that Russia was responsible.
Shortly before the ceremony, the official Pyeongchang 2018 site stopped working, with users unable to access information or print tickets for events. The website was only normalised at 8am on Saturday, 12 hours later.
