Not really sure what you mean? Cable has been fibre since the Telepest & NTHell days. Noone on the VM Broadband service will get less than what it says on the tin as it's the modem and config file that caps the speed, not the infrastructure. Even at peak times the only slow down you will ever meet is when you download more than what VM deem as fair, during which times they will cap you a certain amount. I can't remember what the figures are but IMO they are reasonable. I've been with Telewest through to VM, right from the introduction of broadband in the UK. I started off with a 512Kb line, and have progressed to through the years on the maximum available tariff until 20mb (I refuse to give them the money for 50mb at the moment). Not once during my entire time have I had anything less than advertised. Same goes for everyone I know that has been with them. A lot of people confuse their speed with the download speeds they get on torrents etc, where you will only recieve as fast as the peers can give. The best way to check your internet speed is via newsgroups, even the speedtest.net service isn't very dependable. However, Virgin's ADSL service, I think it was previously called virginmedia.net or something like that, is just as bad as the rest of the ADSL services in the UK. The one major downfall in this case is that the customer service is absolutely woeful making it one of the worst ADSL service providers. That's going from customer reviews and speaking to people who have had it, I haven't had any dealings with the .net service personally. Apologies if this comes out in all the one paragraph btw
