I tracked it down.  Turns out that up until the recent comcast update,
ipv6 travelled safely through my router to the nets.  Apparently, that's
now blocked, and the tracker had an ipv6 address being advertised, which
breaks if ipv6 isn't actually working.  My solution was to turn
off ipv6 on my laptop... when I get more time, I'll also turn it off
in my router so I'm not advertising v6 connections internally.
