I am due to be getting a free upgrade to my broadband from 1Mb to 2Mb.
You should check the T&C's of your new 'free' upgrade. While upping your downstream, BT has taken the liberty to cut back your monthly usage allowance!
http://www.theregister.co.uk/2005/02/14/bt_upgradeIn any case, don't forget BT has upstream restrictions of 256 kbs, so if your hosting anything (P2P, Streaming Audio, Websites), all the downstream bandwidth in the world won't matter.
I just switched over to Bulldog in the UK and am pretty impressed with the speeds. I'm getting 4 meg down, and 512 up which is pretty impressive.
UKOnline offers 8 meg down, and 400 up, but they impose a 50 gig monthly restriction which seems stupid to me. Also, they only offer dynamic IP's.
I think HomeChoice also go up to 4 meg, but I don't know what the upstream is.
