The same thing that happens if the SSH daemon dies, I guess?

FWIW, I’ve been using Wireguard for a while (probably ~2 years?) as an always-on VPN for multiple mobile devices, and also as a reverse tunnel to pinhole service access inside a LAN. The Wireguard config and daemon has been rock solid. The only time it’s failed is when I messed up the AllowedIPs, but that failure occurs at configuration time. It has never crashed, or stopped routing traffic correctly, or otherwise failed in a way that interrupted traffic flows.

That's a good point.

I guess I'll give it a try for some time.
