I am a big fan of Angry Birds games especially Angry Birds Friends on Facebook. I always access the game by typing URL (https://apps.facebook.com/angrybirds). Today, when I tried to access the website through the same URL, I was shown a different page.
You can see the page that I got for the URL https://apps.facebook.com/angrybirds
I think I was given Developer’s Login Page. Heroku is a cloud application platform and I think Angry Birds Friends on Facebook is hosted on Heroku’s cloud. Sadly I couldnt do any thing further with the page provided to me. Hope Angry Birds Friends on Facebook look into this and try to come up with a fix.
