ddox no longer part of dlang.org?

[Steven Schveighoffer via Digitalmars-d]

In Andrei's presentation last night, he mentioned that the new ddox 
documentation coincided with a surge in visits to dlang.org.

However, I just noticed, the link to them is gone. How long has that 
been the case, and can we put them back up?

Also, does anyone know how often the "prerelease" linked docs are updated?
