Heres a quick and dirty rundown;
The site has been moved to a new server and the old server has had its config updated to point to the new servers db. This means we have one db and two 'sites' until everybodies DNS is updated. Because I have fixed the search on the new server, people who are still getting the old server's 'site' will have some problems, but they will be fixed when the users' DNS is updated. (ie, I can search and view new posts with no errors at all).
Hopefully that makes sense, its hard to explain DNS stuff without pictures. Ask any q's, I might have to reply using an ms paint representation.
