Yeah, it seemed to fix itself earlier this evening. I'm not sure what could've cause it; one can only assume that one of BT's big super-duper internet controller things decided to conk out and reduce the bandwidth for lots of people. The effective downstream didn't seem too bad, but the upstream was awful, and as we all well know, you can't have one without the other as the upstream is always disproprtionately low. Well, apart from if you've got SDSL, but it's so expensive. I can't see why they don't give equal down/up on standard connections to be honest, I mean, they can say that bandwidth is expensive, but it's 'them' who set the price of it anyway, so they're justifying themselves by saying it's just 'like' that.
Ok, I'm rambling.
