A photo illustration taken on March 30, 2018 in Beijing shows the screen of a laptop with the word "VPN" written in the search field of the Chinese Baidu website. Chinese authorities had announced that all unrecognised VPN services would be blocked by March 31, meaning that Chinese and foreign companies must choose from a limited number of state-approved VPNs. / AFP PHOTO / FRED DUFOUR (Photo credit should read FRED DUFOUR/AFP/Getty Images)
