Subject: Re: Help finding failure point accessing PLUG Website
Kevin,
Thanks for the information, I am aware that the traceroute might be
getting to the last hop, then get dropped, hence my request that people
who can actually see the website submit some traceroute information.
What I'm trying to do is find the point where a lot of people (myself
included) get misrouted, misdirected, or blocked such that any attempt
to view the PLUG website results in a timeout error, even though I can
see the site if I redirect the request through another site. In my
experience, that's usually a routing problem, one direction or another,
or a problem with the destination server. If other people (preferably
people NOT using COX) can put up some traceroute information that can
help me determine some common routing information for the destination,
then perhaps I can track the problem to a router, or to not being a
routing problem, in which case I can look into other possible causes.
What it comes down to is that I want to find out what's blocking some
people from the PLUG website, and either post a workaround, or get it fixed.

I appreciate the additional information you provided, and you're right,
in that it may not be a COX routing problem, I'd still like to see a
non-COX route to help me verify that. After that, I'll start sending
web requests with various bits modified to see if I can get one to go
through, and thus determine if there is a malformed request issue that
may need to be addressed.
