[44net] Tunnel mesh is (mostly) down

The tunnel mesh went down today at about 08:20 UTC. Most of our routes have disappeared, are no longer being advertised on RIP. The portal.ampr.org site is not responding anymore. It looks like the portal is no longer distributing correct information to the RIP server and so the RIP server sends incomplete broadcasts and the ampr-ripd deletes the routes. Is there some fallback scenario, e.g. loading a last correct list of routes by the RIP server to make the network come back up in the state it was just before the mishap? Rob
