I'm not here to feed the troll, and I don't think what I'll say is implemented for the Unocs website, but technically, hitting a page on unocs.com don't means that the page is on the same server. You can have a frontend and many backends/servers even if you hit the same domain (unocs.com in this case), it can reach several data centers/servers. But, btw, I think you are aware of that.
