Google Base - Forbidden Error 403 on sign in

As of 16:54 GMT I was unable to sign in to Google Base.

http://base.google.com/base/welcome?hl=en_us

I've found this whilst researching keywords this afternoon. I moved to this page on Google initially:

http://www.google.com/submit_content.html

Saw Google Base and followed the link. On attempting to log in I was presented with a blank page (not even Google branded) telling me

Forbidden
Error 403

I appreciate Google Base is in beta but would it not be better to provide a better page than this to the user? see screen shot below:

I appreciate it's beta but I'm left wondering why its set as a plain old Forbidden without any notice of when the page is due back up. Anyone know why Google would do this?

Cheers
