Surely they can't block your access to a site. What happens if you're actually a paid up member of Rapidshare, do Talktalk refund you?
http://rapidshare.com just hangs on 'waiting for rapidshare.com' for ages and then fails, however http://ssl.rapidshare.com works perfectly! Connecting to rapidshare.com also works fine from my phone on Orange Internet, so I can only assume it's the ISP, though I don't know much about ISPs and how they work etcIs Rapidshare down?
Hopefully.
Evil rapidshare and oh yeah, stop downloading porn!
