[outages] Comcast packetloss/latency Chicago Il

19 Dec 2011

      Started seeing High Latency and Packetloss on a Comcast Business Circuit 
in the far Western Chicago Suburbs.  Started around 11:50am CST.  Looks 
like it might be at a cross connect between ATT and Comcast downtown 
Chicago.

Thanks,
