MCI routing loop near Chicago

MCI administrator(s):

Whilst attempting to contact host '64.195.130.100' (NS1.USR.COM).

From Net-Nation (TIER-1 peering with BIG PIPE, LEVEL 3, MCI, VAIX):

For what its worth if someone from US Robotics is listening, neither of
your two listed nameservers are reachable from Western Canada as tested
from Net-Nation, the Shaw and Telus residential networks, and the Telus
business network.

MCI administrator(s):

Ehm... seriously, you as a customer should know the NOC
email address of them, right? At least that traceroute
indicates you are one, or the host from where it starts.

From Net-Nation (TIER-1 peering with BIG PIPE, LEVEL 3, MCI, VAIX):

And that is crap, sorry to say.

Please, post to NANOG if you have to and if there is no way
out. And kindly explain what you did before and what did not
work when you post such stuff.

As Alexander Koch pointed out I could have been more detailed in my post
with respect to methods attempted to notify the relevant parties prior
to posting to the NANOG list.

With that in mind, after roughly two hours of attempting to notify MCI
through the available channels receiving only two responses, both from
MCI (US Robotics can not respond, their poor DNS setup has left me with
no means to contact them via e-mail (NS2.RACKSPACE.COM doesn't appear to
know about USR and their primary is unreachable to me and additionally
through several on-line DNS lookup engines I tried)) I felt that I would
post to NANOG as a last resort.

For what its worth the auto-generated ticket number I received from
MCI's "help4u@mci.com" address was: 2005062102342. The other response
I received was an "Out of Office Autoreply" from hostmaster@mci.com.

Hope that helps,

Cheers,

James

and help4u probably isn't going to fix this as it's clearly the customer's
loop, not mci's... traffic looping from

11 Serial4-8.GW6.CHI6.ALTER.NET (63.84.148.169) 50.191 ms 49.972 ms
50.192
ms
12 mci28259-gw.customer.alter.net (63.84.148.170) 51.314 ms 51.605 ms
52.499 ms

(gw == edge/aggregation device, 'customer.alter.net' == cpe)

is a 'customer problem'. Help4u will likely have responded with a 'not our
problem, but thanks' (or something polite and along those lines). Thanks
though.
