Subject: [Politech] A reply on Chinanet, spam,
     and blocking Chinese networks [fs]


As the senior operational security officer for a large multinational
ISP, I find a particular irony here that many of your readers may
miss:  while Chinanet is busy blocking American universities, a large
portion of the ISPs in the United States have already taken to
blocking all of Chinanet from their own networks.

In our experience, Chinanet is one of the top 3 sources of unsolicited
email, on the public Internet - they absolutely refuse to enforce
their own AUPs, let alone the criminal laws of the EU, US, and other
sovereigns.  Granted, these laws are not technically their problem,
however, these failures have lead to such a significant decrease in
Chinanet's connectivity to the rest of the world that there has been
some (albeit moderate) political backlash (Google is your friend
here).

Chinanet seviced networks also rate very high for other types of
abuse, such as distributed attacks, network reconn, etc.

Interestingly, the vast majority of Chinanet's problems originate with
American customers or "hackers", and this may well be a defensive move
in their eyes.

In short, I suspect there is a lot more to this than meets the eye.
