Hoping someone auditing the list can provide some insight or a back
channel support option.
I started having some good latency spikes last night, which have
continued this morning, so I finally took a look at things and I am
seeing a lot more routing than I expected. Support is telling me this
is normal but I don't remember this many replies on traceroute. My
speeds are about 1/5 the normal as well this morning and seeing some
dropped packets even using a test sight inside Charter's network.
This is just business cable so my support options are pretty limited.

Thanks Shawn. That is more along the lines of what I expected to see.
Are you still seeing odd routing with Charter in Wisconsin? Charter's
routing in Michigan seems to be going pretty crazy at the moment as well.
The following traceroute is from a Charter residential line* in Kalamazoo
MI to a Comcast business (DOCSIS) line in Ypsilanti MI, by way of several
unknown hops, some of which are in RFC 1918 space, Sprintlink possibly in
Fort Worth TX, another unknown hop, then Comcast Dallas TX, Comcast
Marietta GA, Comcast Ashburn VA, then finally Comcast MI. Needless to say,
this is not the normal route:
http://pastebin.com/9CKmea6M
Tracing the same route but in the other direction also yields odd results.
The route proceeds normally to a Comcast ibone router in 350 E. Cermak
(Chicago IL), but the very next hop after that router is the public IP of
the Charter service in Kalamazoo MI as follows:
http://pastebin.com/VCCgnUsn
For what it's worth, if anyone could explain to me what might cause that
behavior (between hops 8 and 9), I would really appreciate the knowledge.
The routing between that same Charter residential service and a
Merit/Michnet endpoint in southeast Michigan is also odd, taking a detour
through Virginia [xe-8-3-0.1018.asbn0.tr-cps.internet2.edu (198.71.47.25)],
which it does not normally do. The routing in that case does appear to be
the same regardless of which side you initiate the traceroute from.
Cheers,
Rusty Dekema
* The Charter residential line's IP address is currently reverse resolving
to a Charter DHCP pool in Bay City, MI, which is over 100 miles from
Kalamazoo. This is also unusual. The Charter service in question is now and
has always been located in Kalamazoo MI.
Well my routing isn't nearly that bad. I haven't been able to get confirmation but support said they are probably just routing around a problem and they can't get any direct feedback form network engineers.
I should get an update tomorrow hopefully. I'm also seeing some bandwidth issues on charters internal network. Something must be going on.
Best to have up and go get some Bells 
No particular issues from where I'm at.
