[jQuery] Jquery.com - UI examples down?

Hello
Bit of a noddy question, but I just wanted to make sure it wasn't just
at my end..
.. is the jquery.com site not working quite correctly, i.e. the
examples don't work on the following pages :
http://docs.jquery.com/UI/Progressbar
http://docs.jquery.com/UI/Slider
So - is anyone else seeing the same thing?
TIA,
Paul
