Google recently made a significant change on their search platform. Users logged on to Google.com were switched to encrypted Google for all their searches.
The company has now announced that they are now prepared to roll out this update to their local domains.
This means that if you use a localized search engine in your country, you could soon be switched to encrypted search by default as well.
This is also an indicated that Google Search Plus Your World might soon be expanded to outside the US market.
