Pingzapper?
I don’t know much about Pingzapper’s safety/reliability, but if you’re already using a VPN and you’re happy with it I don’t think there’s any reason to switch to something like Pingzapper. It’s going to perform essentially the same function using SSH rather than VPN. There are differences, but I don’t think you’d see any boost over what you’re using now.
