Interesting post. I appreciate their candor and self-criticism, but, as a customer, I'm consistently surprised by how robust Tailscale ends up being, and how rarely I've experienced an issue that actually broke my tailnet. The sort of downtime that might keep me from accessing the admin tool or something else like that is rare enough, but my nodes have almost (?) never failed to talk to each other. Pretty great.

Caveat: I have a very small tailnet (<100 nodes). Anyone running with thousands of nodes may have a very different experience where inconvenience might be existential.
