The OZx site got hacked @6 months or so ago. Unrecoverable.. The OZx site owners blew up the rest of the site hence it is off the air-404.
Some of the keys players (Flukey, Craig Hanley, BruceE.) have been re-posting some of the OZx scenery on the ORBX site for the last couple of months - in the Community Scenery section.
