We have been seeing more issues in the last few weeks with our Comcast Business 
customers also. Lots of offline alerts at night. Most in the same geographical 
area and it seems like they are doing different areas each week.

No evidence though from them. When we call them there like what are you talking 
about?

Subject: [outages] Comcast/Level 3 Issues - Detroit/Chicago Areas -- Now 
CenturyLink today too?

Does anyone have any information on some ongoing issues with Comcast in the 
Michigan area since end of April that involve intermittent packet loss, latency 
spikes (from normal 20 ms to 500+ ms), and just overall cruddy paths?

We're seeing issues with 3 of our sites in West/Central Michigan that use 
Comcast Business for Internet as they route from Comcast to Level 3.  
Traceroutes seem to die somewhere in Chicago or leaving Detroit either in Level 
3 or at the edge of Comcast:

Now, this morning we're seeing an inability to pass two-way traffic over 
CenturyLink through Chicago:

Comcast appears blind to the issues we've been seeing at their edge.  Seems 
more like a Level 3 issue.  What's going on in Chicago lately?
