So domain ownership is fine, but depends what they might be doing with the hosting etc, and whether the site is being cached.
for me its on a server currently in germany but depending on country/location - eg outside Europe site might be cached somewhere else.
I have not been onsite for a couple days so not been hit with cookie nonsense or redirects, but looks more like temporary no access to DNS server to give correct info. so redirects - which is wierd - dns propagation from at least 4 dns servers as expected.
TTL is long. so again ok ish.
hopefully it will clear up as seems most likely dns failure to reach what the link actually goes to so the provider redirects to some other crap eg - sites available do you want it sites. annoying but not the worst thing that can happen
