Hola (VPN)

Hola is a freemium web and mobile application which provides a form of VPN service to its users through a peer-to-peer network. It also uses peer-to-peer caching. When a user accesses certain domains that are known to use geo-blocking, the Hola application redirects the request to go through the computers and Internet connections of other users in non-blocked areas, thereby circumventing the blocking. Users of the free service share a portion of their idle upload bandwidth to be used for serving cached data to other users. Paying users can choose to redirect all requests to peers but are themselves never used as peers.
