Well then, my mistake. It's just awful fishy to post something to a weird Apple website, even if it is from the domain, it doesn't look like something that Apple would let the general public see.
Also, the OP's lack of information, lack of proper English, and newly joined user status threw off more flags for me. Then on top of that, telling me that this screwy website is "NOT Bad" throws off a few more flags.
There is way too much wrong with the website. The messed up menu (which can apparently be explained by the lack of iPad button from mrblack927). I also noticed the copyright of 2009 at the bottom, plus the fact that the store button is broken as well.
So, why would the OP post something that looks fishy, admits that it's fishy, but leaves us no information on what it's supposed to do. I'm still unsure what the point of the website is. All I know is that it asks for an email address and the Sales Order number. The OP explains that customer service sent him there, and that's about it.
I don't think I'm "completely bonkers." I think I have common sense. I don't care if it is a subdomain of Apple. Messed up website, weird OP post, telling me to trust it... something doesn't seem right to me.
Also, I do know a little about websites. Obviously I do if I looked at the page source, and the structure doesn't match what Apple uses for the rest of the website. The comments left seem very unprofessional. You're right about the domain hosting. I don't know too much about it, but I do know it's very un-Apple like to have a web address that's completely non-descriptive such as the one posted.
I'm sorry about the mistake.
