The links currently at the top of the page lead to a domain owned by Blizzard. The "tip" also works, you can see a message which reads - "You have no characters on Sam's Happy Funland." Which as far as I'm aware isn't a Blizzard realm (At least not a public one).
The HPPS -> Means a page secured using SSL, like every single shopping site or secure login page on the internet uses.
