Gotte filters?
The part that I was particularly concerned about was where it left qwest
for BBNPlanet and got right back on Qwest. I went ahead and gave them a
call (at the number listed on Jared's page), and they asked for a
traceroute, etc. I gave them all the research that I had done and they
just kinda fell silent when they saw my email to them. Then they said
"We'll have our NOC group take a look at this.". I thought that I had
called the NOC!!!! Yet more examples of clueless morons manning the
phones. (Not saying that my employer is not guilty of the same 
),

The guilty party is AS3908, but the truely sad part is the lack of
filtering from their peers. Pass the pointy hat to bbn and c&w at a
minimium.
http://www.e-gerbil.net/ras/3908 by my count there are around 2500 routes,
most of them /24 or longer (count the /30s). And when you try to email
noc@sni.net...

.. and since various companies keep hiring bright university students
right off the bat, they don't get to spend time learning how the net
works by working in a NOC.
Which means, finding clueful people to staff a NOC is getting more
difficult each day.
Thanks guys.

It's sad when more than 1/2 of your announcements are caught by the
filters.

Each hop in a traceroute represents a -new- packet (actually 3) being
sent out.
Hence "Hopping back upstream" during BGP flap state.
Remember "The Matrix" ?
There is no spoon.
