The first report of Netflix blocking a VPN comes from uFlix, an Australian VPN service that charges AUD$2 (£1) per month for the ability to view Netflix content from around the globe. When blocked users try to access Netflix they are seeing the following message: “You seem to be using an unblocker or proxy. Please turn off any of these services and try again.”
