>To put the market in perspective, there are VPNs that only work if [...] UDP isn’t blocked

isn't that true with WireGuard/Tailscale too?

Tailscale employee here. Tailscale has a fallback that does connections to a relay server called DERP. DERP works over HTTPS, so if you can't access the outside world via HTTPS then you have much bigger problems than Tailscale not working.

Is DERP raw HTTP or based on WebSockets?

derp seems to be its own protocol.

tailscale seems to prefer websocket transport for derp frames: https://github.com/tailscale/tailscale/blob/505f844/derp/der...
