i hate this "i want it cheaper mentality."
you get what you pay for. cheap = bad contention on the ISP's pipes + shaping/throttling.
This is the way ADSL works....It's what's called a "contended" service.
Based on current BT pricing levels, a 622Mbps central "pipe" costs an ISP around £160,000.00 per month. On an un-contended service (i.e. all users are guaranteed their full 8meg at all times - actually 6.8Mbps is the maximum speed from ADSLmax), this works out to around £1,750.00 per customer, because a 622Mbps pipe can only fit 90 odd users running at full speed.
Based on the assumption no customer wants to pay £1,750/month for their ADSL connection, the ISPs share it out between their customer base.
If they put 5,000 users (instead of 90) onto a single pipe, the cost (per user) drops to around £30/month per user.
As you're with an ISP that charges an awful lot less than £30/month, it's fair to assume they are cramming more than 5,000 users onto a single pipe (probably more than 20,000 users, bringing the cost they have to pay BT down to under £8/month).
The lessons to be learnt here: -
1. Don't go with the cheapest ISP you can find (unless you're happy to put up with rubbish speeds during peak demand).
2. What do you expect for £10/month?

what about the ISP's that are on unbundled LLU?
lol, have you ever read http://www.skyuser.co.uk/forum/sky-unhappiness/ or http://bbs.adslguide.org.uk/postlist.php?Cat=&Board=sky ?
sky are one of the worst.
it still works the same way, they just cut out contention on the bt DLAM's at the exchange, but with the amount of customers they have on their own equipment at the exchange, they will more than likely be experiencing contention there too. i know the figures for the pipex MSAN's at bt exchanges, and trust me, it doesn't take many customers maxing out 8+mb lines to really hammer the available bandwidth.
the advantage of llu providers is a lot of the time they have faster fix rates on certain types of fault, and they also don't use the BRAS profile system.
the info i posted that you quoted, that still works the same. llu customers are still on the same pipes as ipstream customers.
