WhatsApp has been blocked in China, as the government appears to be cracking down on the Facebook-owned messaging app ahead of the Communist party congress next month.
The messaging app, which has more than a billion users worldwide and protects messages with end-to-end encryption, has not been available since Sunday. WhatsApp is the only Facebook product to operate relatively unhindered in China.
The service has been disrupted several times in the past few months, with many users complaining they have been unable to send videos and images without using a virtual private network which circumvents China’s “Great Firewall”. But the service has not previously been taken entirely offline and has usually returned to normal in quick time.
