Is jQuery UI Themeroller broken?

Is jQuery UI Themeroller broken?

I have tried to download a theme created by someone else, a theme created by myself (just to check that the URL I received was not broken), and a theme from the Gallery. The only one that works is a theme from the Gallery - all the others return a " 504 Gateway Time-out" error message.

Is anyone aware of this problem? Has anyone else actually SEEN this problem?

Thanks
