Hi Davey, Manu,

The server we operate in Guangzhou was indeed reachable from outside China. This is not the intention, of course. On Saturday, when we got notification about this, we withdrew the prefix from the server, and we are communicating with the host to solve this.

Many people have already said this, but I'd like to make it clear that the K-root server was NOT emitting false responses for Facebook and WhatsApp. The responses were being modified by something between the server and its clients.

Regards,
Anand Buddhdev

If it is urgent, I suggest the K root operator withdraw the route of the
instance in Guangzhou immediately.
