3.0.0 is so popular that no one can access the openoffice.org website right now.
But its bouncer and mirrors are working well.
If you would like to get 3.0.0 en_US for Windows, try the bouncer;
http://openoffice.bouncer.osuosl.org/?product=OpenOffice.org&os=winwjre&lang=en-US&version=3.0.0
Or you can try the mirrors and check your mirror's directory such as .../stable/3.0.0/
If you would like to get 3.0.0 localized versions, for example, Japanese, check your mirror's directory such as .../localized/ja/3.0.0/
And it is a very good idea to check the QATrack.
http://qatrack.services.openoffice.org/
Go get it!
PS: QATrack is one of the Sun Open Source Community Innovation Award winners.
