When Oracle acquired BEA, they took them offline for awhile.
This sucked, as the BEA products seem to demand frequent trips to the online references, and troubleshooting guides. Actually, it still sucks, because although they have replaced most of the documentation that was available (the most valuable bits were the dev2dev and forum areas) they often link back to BEA, which redirects you to Oracle's front page, or to the front of their BEA documentation section, but absolutely never to anywhere resembling where the link was intending to go.
For the moment I wouldn't worry and would expect them to come back ... although maybe they'll need some prodding for some of the things that fall through the cracks.
