What interests me is that there are clearly multiple pools of bandwidth - the international speed issue was fixed for me quite some time ago; I'm currently getting 3-4 MBits/sec from the US, and the LA speedtest shows ~3200k/sec. As these speeds are about as fast as my phoneline can handle anyway, I'm pretty happy.
Not sure if it makes a difference, but I'm on a 58.28 static IP, fullspeed down, 128k/sec up.
