Accessing one country’s Netflix from another country requires you to connect to a server that is located in the country whose Netflix you wish to watch. By connecting to a server, you get a new, server-owned IP address that allows you to appear to be located in the same place as the server itself. However, if more people end up doing this with the same server at the same time, it won’t be long before Netflix’s systems figure out that something is wrong. With multiple people using the same address to connect to Netflix and watch its content, the service quickly figures out that this must be a VPN-owned IP, which is then blocked.  As a result, you will lose your ability to stream Netflix content, which is why Netflix VPNs tend to constantly fight the same battle of replacing servers and addresses in order to replace the ones that do not work anymore.
