probably depends on how the internet is done routing. That is
how the internet traffic is passed to/from your machine to intermediate machines and eventually to intermediate
machines. Its the same reason why some US sites load
quickly and others load very fast.
In a command windows type:
tracert <address>
where address is a destination domain or an internet address.
it will tell you the route the traffic is taking to get to the
destination address.
Try using trade2win from a few different sources to check the
speed.
