It does until it doesn't. Then you have to wait X seconds for a keepalive (one of the 100+ configurables) to notice you're not passing traffic, and your client to tear down the dead tunnel and reconnect. Meanwhile many other applications have also lost connection to endpoints and need to do the same type of reconnection.

Stateless is the best feature of WireGuard IMO. I'm really looking forward to the mobile clients stabilizing.
