I am adding a new VPN for testing today - StrongVPN. The Windows software GUI layout is very complicated but it has some good advanced features. Unfortunately their OpenVPN TAP driver is not signed and requires putting your Windows computer into a special mode called "test mode" so that unsigned drivers can be used.
I tried to connect to many PPTP servers on ExpressVPN not only Los Angeles and Hong Kong. It appears that their PPTP service is completely blocked and they are not taking corrective actions to unblock it. The OpenVPN is still working good though although occasional re-connection is necessary.
Here are the speeds.
