So Gabs spotted last week that Google was testing removing the "pages from UK" radio search button at Google UK. He was the only one I saw mention that until now, but I blogged it at Search Engine Land, because I knew it would come up again.
Today, I spotted a thread at Google Web Search Help with complaints from some searchers that Google South Africa is no longer showing the radio button "pages from South Africa" only. They are pretty upset about Google dropping this. Keep in mind, it seems to be a limited test and Google might not go this route.
Here are some screen captures from Gabs:

To make up for the lack of the radio button, Google will add a link to the bottom of the search results page that shows: "Show only results for United Kingdom."
