Most of us use Google for searching purpose. In most country, Malaysia for example, Google have their own domain, www.google.com.my.

Most of the time, when you type www.google.com in address bar, it will redirect your browser to www.google.com.my.

You can bypass this redirection by typing www.google.com/ncr. This URL will serve you the real Google homepage.

NCR at the end of URL represent No-Country Redirect. I guess.
