The University of Melbourne currently manages the DNS server munnari.oz.au. A decision has been made by the University to shutdown this server.
*sniff*. First the CS department votes to move from cs.mu.oz.au (where it's been since Australia first got connected, if you assume that cs.mu.oz and cs.mu.oz.au are basically the same thing) to csse.unimelb.edu.au, which was sacrilege enough, but now they shut down munnari? The DNS records for .au already appear to have been updates, so muway (in the form of muwaya) is the only unimelb server on .au.
Sigh.
