I am having a problem reaching what should be an easily reachable
server going through 4 ISPs. I have no problems pinging or
tracerouting to other hosts on the Internet. The target server is
reachable from just about anywhere except the DSL connection I'm going
through. The route goes through four ISPs: Xspedius, AT&T, Qwest, and
Speakeasy. Each one either states the routing problem is not on their
network or their noc is non-responsive. This has got to be a routing
or subnet mask problem with one of them.

I'm trying to reach 66.93.249.81 (a Speakeasy IP). The trace gets to
the speakeasy network and then dies. The last two hosts in the trace
below (13 and 14) are un-pingable as well:

Similar (yet not exact) routes from public looking glass servers have
no problem. The target server is VERY reachable.

Any suggestions as to where the routing problem is, and once
identified, who to contact so that something will actually get fixed.
I've worked the issue from the Speakeasy and the Xspedius ends, but no
one wants to own this problem. Extremely frustrating.

Thanks in advance. You can email me directly: bill @ 0spam.net
