To be fair, in the US (which is what we're comparing all of this to), broadband is defined as 25Mbps up/3Mbps down.
Ah - by that definition much of central London doesn't have broadband as I get 8 down 0.5 up and can't get much better. Still I find the 8 it basically fine. Maybe the vid is 720p rather than 1080p - whatever.
