Due to international laws and varying copyright agreements from different countries, Netflix content can vary greatly from country to country. That's why some users use virtual private networks or VPNs to work around this issue. VPNs give the international users access to Netflix by letting the service think it is connecting from somewhere in the US. It's not as big an issue for copyright holders but it has gotten the name of "geo-piracy."
Torrent Freak discovered that several VPN services like TorGuard are starting to see more errors from users trying to connect to Netflix. According to Netflix though, they haven't changed the way they handle VPN connections. It could be Netflix is testing something out but won't tell the public just yet. You could consider it a warning that Netflix might be cracking down on "geo-pirates."
