Tor doesn't detect when the world cannot reach it anymore

This is Tor r14297. When my internet connection dies (as it does every 24 hours), and I come back up with a different IP address, Tor doesn't seem to notice that the world cannot connect to it anymore. This used to be different in the pre-RC versions, I haven't checked the previous RCs for that behaviour. Even after 6 hours, Tor has nothing in the Notice-level log.
