HPGRelay is running BrokenVista 24/7 at the moment, I believe - although obviously the pings will not be fantastic unless you're Australian. I think most US players get ~200, which in my book is still playable at least.
The map is very close-quartered, and works quite well for small (4-6 players) games, much more so than Jungle and Glory. Only two quibbles with the design:
1) Falling off the edge and into the deep water kills the pilot but not the 'mech, so you get a lot of radar ghosts after a while.
2) You don't seem able to repair at the spawn points. If this is intended behaviour then obviously I don't mind, but if it's supposed to be possible to repair there then this needs to be fixed.
