The actual ADSL Max line rate supportable will be determined during the first 10 days of use, after which time the highest stable rate possible will be set."
This, combined with the increased competition in Broadband providers, means that price plans have moved quite a bit since the village was first enabled in Summer 2005. For instance I will now be moving my ADSL provider to Eclipse (the ad on the left) where, for £14.99/month, I should, according to British Telecom, be able to get a 4.5Mbps connection. That's 9 times faster than the 512k connection I currently have for the same money, or around 90x faster than dial-up.
Eclipse is certainly a good deal at the moment, and is very worthwhile looking at.
