[Outages] Level3 routing failures in Denver

[Chris Stone]

Thanks - looks to be a Cogent problem - rerouted some traffic to use my Level3
connection and the inaccessible sites are accessible. But Cogent isn't routing
the traffic - just dropping:

[root at mail root]# traceroute corp-mail.uniserve.com
traceroute to corp-mail.uniserve.com (216.113.192.13), 30 hops max, 38 byte

But through level3:
