I think people are just going to see a traceroute determining packet loss and not going to read the rest of what happened. Just going to shortcut to an answer.

Hi all, 

Anyone beyond front line support at cogento on list? 

Nanog is the last place I'd look for assistance but it seems support 
over at cogentco is not nearly what it used to be. 

Example MTR to cogen't own website (support doesn't utilize or 
understand MTR at all apparently):

6.8 0.6 
9. cogentco.com 4.1% 196 2.1 2.0 1.0 
16.8 1.1 

Pretty much the same to anywhere. Packet loss begins at rcr22.iad01 
and propagates all the way down the line. Worse during peak hours, 
gone late at night. 

After three days of no email response for my ticket, I called and after 
an hour of my life I want back, front line support cannot reproduce the 
loss. Final conclusion: "Your host is dropping packets".
