A WebmasterWorld thread has one SEO claiming he is no longer able to use a VPN to track Google search results in a different country.

This SEO is based in Singapore and uses a VPN to access the U.S. Google search results. He sad recently that stopped working and Google is detecting he is using a VPN and thus showing him the Singapore results.

He said:

No one else in this thread confirmed the issue, but he said people are complaining about it in the member only SEO Book forums. I cannot verify that simply because it is member only and I cannot discuss what is going on in there.

Have you noticed this issue? I don’t see how Google can detect you are accessing a computer in the U.S. and figure out to show you different results on a machine within the U.S. Something doesn’t sound right here.
