Downstream Bonded Channels Incrementing Corrected and Uncorrected Errors-Ranson, WV

Xfinity,

 

Please pass this on to the NOC and Head-End that serves Ranson, WV.  I'm seeing the blue down arrow blinking on my modem and looked into it and am seeing millions of incrementing corrected errors and double digit uncorrected errors on bonded channel 28 which is using OFDM PLC modulation instead of the QAM256.

 

See below these stats directly from the cable modem (Motorola MB8600):

Thank you,
