Google Haunted House 404

Are you getting a 404 error on the Google homepage link? The link in question is:

Apparently it is an issue which is only affecting countries outside the US. To take a look at what should be there visit this proxy or any proxy based in the US:

Choose the “United States”, enter the URL, “” and click on the link on the Google Homepage.

I’ll see if I can find out more about why this is happening or whether Google are purposefully restricting people outside the US.
