Popular messaging app WhatsApp has suffered serious disruption to its service in China.
According to the Open Observatory of Network Interference (OONI), network measurement data suggests that Chinese internet service providers started blocking access to WhatsApp on Saturday. Public reports on Twitter indicate that WhatsApp, which is owned by Facebook, became inaccessible for some people a week ago.
In China on Tuesday, users reported intermittent service on the messaging platform.
Over the last few months, there have been a number of WhatsApp disruptions in China. WhatsApp declined to comment on its status there.
