ATTBI is my ISP. During the past week, I've suddenly lost access to a couple of sites in Hong Kong related to human rights issues in China. (Both sites are hosted by the same company.) But when I try to access them on a networked computer at Berkeley, they come up fine.

So, I ran traceroute on both systems to see what was different. Turns out that AT&T routes the request through China, where the government censors routinely block access to sites like these. (The two other working routes I've seen use gblx.net nodes.)

Does anyone know how to get this issue addressed? Seems like it should be a relatively easy issue for the right person to resolve, but I dread the idea of trying to explain the situation to one of ATTBI's customer service morons.

Thanks,
jdr

on both tracroutes at which point does change? there is really nothing you can do, but try and get a dialup account thru Berkley if you can? they might be using RF to get through the firewall...

To clarify: the normal route (the one that other servers -- not just Berkeley -- use) is *directly* to Hong Kong via Global Exchange. It's just that AT&T's server doesn't seem to know how to find that route.

The problem is that even though there are many ways to route directly to Hong Kong, AT&T chooses to do so through China. It's when the packet tries to pass from China to Hong Kong that it gets blocked.

Probably the only thing you can do is look for a web proxy to connect to that can forward your request via a different route.
