Blocked by Virgin Media

So I can't get onto this site from home at all. Tried Linux and Vista machines, multiple browsers, and every time I can't even conenct to the web server.

I think Virgin Media do shennanigens with blocking connections to certain sites. Anyone else getting here ok through Virgin?

I don't like the sound of that... can you ping/trace the site at all ?

I'll try it when I get home. Is it OK if I communicate with you via email about this (since I can only post here from work and can only reproduce the problem from home). Could you email me the IP address, and I'll try pinging that too?

OK, tried pinging, ping can find the IP address so the DNS thingy is OK but there's no repsonse from the server.

I'm deeply suspicious of Virgin blocking random sites every now and again - they blocked the sourceforge/slashdot site a couple of months ago which was a PIA. Currently, I also can't get to dilbert.com from home either.
