Many of the well known websites determine your location based on your IP address and restrict their content or functionalities based on the country you’re in. Some examples are Gmail (Germans get only @googlemail.com-addresses, legal reasons), YouTube (content is restricted by the GEMA), and Pandora (limited to US citizens) to name only a few. To circumvent these restrictions, being able to quickly get an IP address outside of your own country is most helpful.
To do exactly that I wrote a little script that will start your very own US proxy server in one minute using Amazon EC2. In combination with browser plug-ins such as FoxyProxy, the script enables you to route all your web traffic through a proxy on an Amazon-owned machine — with an IP address in the US, Ireland, Singapore, Tokyo or Sao Paulo (location of Amazon data centers).
