As far as I understand it, the binary contains compiled-in ip addresses for public nodes operated by zerotier. By recompiling you can run your own, they are not special in any way as I understand it. And if they go down your network wil not suffer, they are only used for initial setup.

Separate from this you also have to option of running your own network manager. This will allow you to create and manage your own virtual networks, with your own GUI, billing etcetera. The Zerotier binary can be compiled with a special option to extend the build-in REST API for that.
