How secure is private networking?
If I have a docker swarm cluster communicating over the private networking feature of Digital Ocean, is that traffic able to be seen by all of the droplets in the region? For example, can a droplet owned by another digital ocean user attempt to join my swarm cluster? In general, how "private" is the private traffic.
Also, can a droplet from one region talk to a droplet in another region if both droplets are owned by the same account?
