data server
Here is the way I understand Tailscale to work. Feel free to correct any misinformation.
Tailscale doesn’t operate ‘data‑center’ servers that store or forward your traffic.
-
Control plane: Holds device metadata, public keys, ACL policies, and the DERP map. It is a small, highly available service that all clients contact only when they start up or need a policy update. Tailscale runs this service on a handful of cloud providers (primarily AWS and GCP) in the United States. TThe service carries no user data. Only control information.
-
Data plane: Carries the actual packets between your devices. After the control plane tells two devices how to reach each other, they open a direct WireGuard tunnel that is end to end encrypted. There are no dedicated ‘data servers’. Traffic travels directly between the peers. If a direct path can’t be established because of strict NATs or firewalls, the connection falls back to a DERP relay. The DERP relays are the only servers that ever carry user payload.
However, to keep with your fear of the US having all your Tailscale keys, what makes you think that Australia, Brazil, Canada, Finland, France, Germany, India, Japan, or the UK wouldn’t/couldn’t do the same? I’m no shill for Tailscale. AFAIC, you can either use the service or not. Your choice, no skin off my back. I’m just curious how far the paranoia rabbit hole goes.

Understandable. I don’t know what your threat model is. I don’t trust any of them except to do what is in their best interest, globally. However, there is nothing stopping Australia, Brazil, Canada, Finland, France, Germany, India, Japan, UK, or even your country, from doing the very same thing. Governments make laws for citizens, not themselves. Everything can be compromised at any time a government decides to. That is the reality of it all. If I am going to have to hide my online activities from a government in 2026, then game over, and there’s not a damn thing I could/can do about it. I’ll just unplug, and live out the rest of my life in the seclusion of my farm/compound.
