Tiscali truely suck balls!
I check there server status daily, because working for the Tech Guys and being on a software/ hardware line, I mostly get internet related calls, and Tiscali barely have a day go by when they dont have a server issue in some way shape or form... Hell they make a big fuss when everythings running ship shape!
BT and Virgin Media are two of the best in my opinion... Aaron bitches about VM but they only real bad thing about them is there tech support, it's terrible. "Plug your router into your modem and turn it off please" - What the hell?!
Rob B has a point though, really, there isn't a truely GOOD ISP out there, every single one has something that's f**ked up about them.
