It seems the Dark Angels FAQ that was listed was not correct, or an older version that was not supposed to be up. So it was removed, and I am sure we can expect a new one up very soon.
Here is a link to the article on Bolter and Chainsword.

Last week I sent an e-mail to Black Library asking if there was a new DA FAQ on the way. It was a bit of a shot in the dark, and here is the response I got:
Thank you for your email, my apologies for the delay in my reply. The Dark
Angels FAQ was a old one and was posted by mistake, A new FAQ will be
available in future.
