It seems after the maintenance today, the address of the D3 website became
https://diablo3.blizzard.com/ instead of
https://us.diablo3.com/ and we can no longer choose the region of the website we want to visit from the region/language menu at the bottom.
Making matters worse, the server automatically redirects us to whichever the closest region forums and leaderboards based on our ip address. As matter of fact, I had to use my browse history to find the address of US forums to be able to come here and post this.
Do you have any idea how stupid this is? I certainly hope this is an oversight and you get the web team to fix it and let us change the region we want to visit asap.
