I'm pretty sure that using the http://www.accessgrid.org/registry/peers.txt 
  as the registryUrl will work if you start a bridge now, since the  
DNS pointer for www.accessgrid.org has been changed to the new site  
and the new site's registry/peers.txt contains the correct address of  
the registry itself.

Long running bridges started with the same registryUrl but before the  
DNS redirection are registered with the old registry and therefore  
don't appear after a purge in the VenueClient. Restarting those  
bridges should make them visible again after VenueCLient purges.
