Supposed to be 50meg 
Our servers in a data centre in London on the internet 'backbone' get a varying speed from these tests, anywhere from 2Mb to 80mb, even though they have 1gb network cards and gig+ links between said servers and our providers & peers. Take those test results with a pinch of salt as the servers doing the testing may not be able to handle that much data at that particular time or at all, lots of other factors too.
Pity you can't use the BT Speed Test service ........
