As you already know, Google is automatically redirecting to your country's Google domain. This is called geographic targeting. Google determines your geo location by searching your IP address in a IP-to-location database. But what if you're searching some code or english content and you're in Botswana? Google will favor Botswana results, and this is not always desirable.

http://www.google.com/ncr

 Simple and effective. NCR=No Country Redirection.
