Charter routing issues

Sat Jan 25 02:16:14 UTC 2014

Hello,

Can someone from Charter Communications enlighten us to if you are 
having any issues or reach out to me directly.

We are seeing some interesting traceroutes from St. Louis, Mo to St. 
Louis Charter customers via Level3, Qwest, or Cogent. Packets are being 
sent all over resulting in traceroutes 20 hops long.

We are also seeing high latency between Qwest  to XO for some routes.

Inbound traffic routes seem normal but latency is high.
