Yep.

The Informationfreeway slippy map uses proxies. Since the new server
move, I am not aware of any reason why you would want to use a proxy
over the main map: I would suggest you just use the
tah.openstreetmap.org URL. However, what was being stated is that i you
right click on an image and 'view' it, the URL won't match that if
you're using the Default InformationFreeway view -- because it includes
the proxies.

The new tah server is severely underloaded as far as serving tiles goes:
speaking as server administrator, I have no compunctions about
downloading any amount of data you need from that API at this time. (If
this changes, I will mention it somewhere, but the host of the machine
is always complaining that I'm not using enough of the CPUs ;))
