Google's Image Labeler Promotion Goes to Page Not Found

If you visit Google Images in the UK, you get a little promotion for Google Image Labeler that reads:

Want to help improve Google Image Search? Try Google Image Labeler.

The link to Google Image Labeler links to http://images.google.co.uk/imagelabeler/. But if you try going to that page, up comes a page not found error.

Not Found

The requested URL /imagelabeler/ was not found on this server

The US version of the URL does work at http://images.google.com/imagelabeler/.

Funny that a Google promotion link is linking to a page not found error.
