Multi-homed condition unknown and suspect due to truncated BGP path.
Approximate bandwidth from the core to this point on the network 
from us at this point in time: 34.56kbps, or a good modem line :-)

 hop       packets   min rtt BW
(ttl)     in    out   (mS)  k bps   Address
 MTU=8166  MTU=4352  MTU=2002  MTU=1492 TT
= 10      9     13  53.55 =  34.56 208.195.108.8 root.starfire.douglas.ma.us

> hp.manhattan.com.     172800  A       199.103.194.137

Aggregated by (and complete path from) Open Advisors.  Appears to be
multi-homed.

Approximate bandwidth to this point on the network: 65.28kbps, or a 
                                        single-channel ISDN equivalent.
 hop       packets   min rtt BW
(ttl)     in    out   (mS)  k bps   Address
= 15     17     18 318.58 =  65.28 199.103.194.137

> DONTSERF.MAKEWAVES.NET.       172800  A       204.94.43.1

Alternic under a different name, operated by Diane Boling, and running
with both nameservers on the same subnet.  Linked to Seanet, which appears 
to be multihomed.

Approximate bandwidth to this point on the network:  629kbps (my god, they
have one root with a  fractional T1 worth of bandwidth available!)

**** NOTICE:
THIS NAMESERVER IS ALSO RUNNING WITH RECURSION ENABLED AND IS NOT A TRUE ROOT.


I rest my case.  Only one of these has anything approaching reasonable 
connectivity, all appear to be off single-point failure circuits (except
possibly manhattan.com), and all are running in non-RFC2010 mode.
