That seems independent of my own internal connection problems,
but worth taking up with my ISP on Monday. Meanwhile, can you
ping any other hosts in the 50.1.20.31-24 range? All are up
at the moment. Hosts 28 and 24 are the troublemakers. 

If anybody cares there's an ascii-art network diagram at
http://www.zefox.net/~fbsd/netmap

Not sure it'll survive the mailing list, but here goes:
