On Sunday 19th August, www.diablo3.eu was forwarding people to a 403 Forbidden error, along with most of Blizzard Entertainments .eu domains.
Diablo3.eu is now forwarding people to the Diablo 2 Expansion website.
Before the 403 Forbidden error and now the Diablo 2 Expansion site, diablo3.eu forwarded people to the World of Warcraft demo page.
www.blizzard.eu, www.warcraft4.eu and a host of other Blizzard owned .eu domains are still forwarding to the 403 Forbidden error.
This change comes 2 days before Europe's biggest gaming event - the Games Convention in Leipzig.
