[Darren] Given that the server is now routed via a different ISP, the problems you had last year, and the lack of serious complaint from anyone else, I'd still (unhelpfully, I admit) lay the fault at the door of your ISP, or some route near to you. Do you have problems with other sites?
[Rosie, Darren] I've tried a number of online translation services... with little luck. Can't work out your first word, Rosie, and I'm completely stumped on Darren's!
