Not really - if you look at the DNS records, they have a TTL of 3600
seconds - an hour. If the name servers go down, or someone fscks the
zone file, the name disappears in 60 minutes. This is normally used
by spammers when they know they'll be kicked off a network, so people
querying for the name will get the address of the "new" location.
The rDNS resolves to 'unknown.ord.scnet.net' (also with a TTL of 3600)
which is also quite typical of a spam operation. Doing a whois query on
the domain comes up with mainly useless information, including the fact
that the domain name servers are ns1.servercentral.net and
ns2.servercentral.net. I've had some difficulties with that hosting
service in the past. Your mystical disappearance could have been caused
by servercentral.net screwing up again.

diff -bw should be able to tell - but what does this have to do with
Linux, SuSE or otherwise?
