Level3 funkiness

Wed Apr 15 20:36:29 UTC 2009

Listen the two are different, level3.com, and level3.net, the two are
colo'd at the same place, thus the reason for the Denver "dying" end
point.  It's .net as you can see; try surfing to 4.6 8.95.11 yes,
4.68.95.28, no...It's just how the DNS PTR for the box is set.  It has
nothing to do with the naming convention of the routers or other network
elements.  Are the two confused?

In Chicago, traceroutes are dying in the same place (Denver). Peered out
