Well, yes, now I do. Only because i'm going thrue the Guarster anonymiser proxy.

Strangly enough, since about two weeks, I can't reach this forums from any given Internet access I have, that is, from home and from my university.

From any of my boxen (2 gentoos, a Freesco router and a win2k) and in different configuration, I can't connect. For example, if I try with Moz and bypassing my squid proxy, I get "Document has no Data". If I try with Privoxy + Squid, Privoxy (1st in the chain) complains that the connection has failed.

The IP resolve if I ping forums.gentoo.org (66.250.107.251). I tried emptying all caches, tried different browsers (even lynx) and even tried different locations (university), the only way I have (finaly) found to connect, is thrue this anonymizer service.

What is wrong? I'm clueless. It is the sole site I have problems with.

HELP!!!! :'(

Here is my current traceroute from my router to this forum:

I notice there is a 10.1.15.106. I tought I had a conflict with that address since my router is using that class range for one of its nics, but I think it's properly configured so that such thing does not happen:

Did you check the other thread near the very top of this forum? Problme accessing the forum. Since you are in Canada also, perhaps it is related.

There have been several reports of sustained connectivity problems lately, and the domain or ISP videotron.ca keeps popping up.

Videotron is a cable bradband access. I'm with vif.ca which is a ADSL access. My university is connected thrue risq.net (?). Non are related.

the problem seem to arise in the 66.250.*.* subnet somewhere. at cogentco.com which seem to be much closer to gentoo than it is from the clients.

[UPDATE=march 10]

Seem to be fixed now. Thanks to who ever fices it.
