Hm, I wonder if that might have been the reason behind some of my high ping times:

I think the two interesting ping times that stood out were:

  6.|-- ae-4-0.cr0.chi30.tbone.rr.com            4.5%  1000   27.1  27.9  22.1 101.2   6.9
  7.|-- 66.109.1.40                             15.6%  1000   24.1  29.9  21.2 108.4  13.2
    |  `|-- 66.109.1.42
    |   |-- 66.109.6.155
    |   |-- 107.14.17.147
  8.|-- ae18.edge2.Chicago2.Level3.net          33.8%  1000   24.1  29.5  21.2 117.4  11.4
  9.|-- vl-3604-ve-228.ebr2.Chicago2.Level3.net  6.1%  1000  129.1 122.6 117.4 190.4   7.3
    |  `|-- 4.69.158.50
    |   |-- 4.69.158.58
    |   |-- 4.69.158.54

Full mtr report here, http://git.io/C_QgVw
This is a mtr report going in the opposite direction, http://git.io/UKyWzA

It seems that the last hop from TWC to Level3 and the first hop into Level3 in Chicago seem to
always have a problem if the route goes through there.
