Cogent Router dropping packets

Thu Apr 17 21:15:24 UTC 2008

Thank you, the issue seems to be fixed now at Cogent.

Does anyone know how often issues like this seem to crop up?  I'm wondering
to see how hard I should push here for routing around cogent for networks
our customers connect from.

Just spoke to cogent about another issue, said they only know about issues
in Los Angeles. Nevertheless, 877.726.4386 or support at cogentco.com
