Hola is an easy-to-use add-on that lets you access these hard-to-get sites with a click. While you are on a site that’s inaccessible, just click the Hola icon in the Chrome toolbar and access should be restored. Internally, Hola is just a VPN service but it hides all the technical details from the end user and requires absolutely no configuration.
You may also use Hola to hide your actual IP address from sites.
