Because VPN only requires an internet connection, it is widely available - more so than any other method of connecting locations. The internet is the world's largest network and its global reach is unparalleled. It is likely that no matter where you locate, a VPN connection will be your most available option with a minimum of setup and connection time. Point to point usually requires provisioning (aka setup time) on both ends. This can extend the lead-time from the time it you place your order to the time the line is operational. With VPN you can be up as quickly as possible, and instantly connected to multiple locations.
