Steps to reproduce
1. Go to minecraft.net/infdev
2. Read the screen.
3. It says not found.
On wayback machine, it shows up. I remember this back in 2010, and I just want to play it on the site. With sound. The launcher isn't really look right. Is dinnerbone trying to fix this with the nostalgia uploads, i hope.
Also, /indev/ version doesn't work.
I might think this is works as intended, because the webdevs at mojang are getting rid of classic.
Intended and not a Minecraft issue.
