level3 issue in chicago (was: FYI, Level 3 issues in Dallas)

like david below, we've been getting reports this morning from customers 
unable to reach various web sites.

investigating a number of these reports, the one commonality is level3 
in chicago. sites are reachable from level3/cincinnati but not 
level3/chicago.

traceroutes make it one hop past our bgp peer and seem to die there.

for one particular remote web server (node1104.follett.com, and possibly 
others) traceroutes and pings from level3's looking glass (using chicago 
as the site) complete successfully, while neither does when ran from my 
gear through the same site.
