Nope, I've had issues as well. I'm going to be rehosting a javadoc repository for it soon, working on setting it up. Edit: You can view my new javadocs hosting here: http://docs.codelanx.com/
They got taken down because of a DMCA request from Wolvereness since he wrote some of them (I think).
I don't believe so, maven repositories and numerous other sources have been down since august, but javadocs has just had intermittent uptime this last week.
