Hi All,

we are having an anamoly occur on our network where our Internet link is experiencing 100% utilisation and the proxies are reporting massive downloads from Czdlxy.163.com  but the traffic does not seem to come inside our network to workstations, just to the proxies.

Czdlxy.163.com appears to be related to some Chinese Online Gaming website (but translation makes it difficult to pinpoint exactly).  This makes me think that either:

1)       Proxy servers are compromised and are hosting content
2)       Denial of service
3)       Traffic is actually going inside our network and we cannot see it (at this

I  realise this is basic informatin but has anyone heard of this site before or do they have any suggestions or thoughts on what could be occuring?  Is anyone else seeing something similar?
