Changing servers? You base this on what?
Let me tell you (and this is fact) that their domain name has expired and they haven't renewed it. Nothing more. Nothing less.
NOTE that i said "MAY", not they are, or 'IS FACT', this is an assumption. I am not disputing the fact it has lapsed. But i would like you to you try and get it! u can not yet.
According to Melbourne ITs domain register their domain has expired as of yesterday
There is a renew prohibited flag that will come up once the domain becomes available, this has not yet happened, so they have time to CHANGE servers and renew the domain name..... fair assumption i would have thought.
