[dns-operations] K-root in CN leaking outside of CN

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.
