Apparently the domain name http//www.diablo3.eu now leads to a forbidden 403 page along with http://www.blizzard.eu. Previously diablo3.eu led to the World of Warcraft demo site but now leads to this 403 Forbidden page.
For those of you who visited the Wrath of the Lich King site before it went live at Blizzcon, you will know that exactly the same thing happened then.
