After nearly two years without an update and a broken URL for over three weeks now, it appears that Back 2 The Roots, the largest source of legal Amiga game downloads, is dead and buried.
The hosted sites are still up and running (e.g. UAE Discussion Board, EAGER, etc.) as well as the Aminet mirror but the main site and the game downloads are no longer accessible, the co-founders have long since moved on and the server administrator has not provided any information about the issue.
It's not looking good.
