Possibly Misbehaving Upstream Node

For about a week now I have been having fairly large packet loss (anywhere from 10-70% depending on time of day) at an upstream node from me (currently 10.39.0.1, strange to me that this is a private block /8 address but I am unfamiliar with Cox's network internal structure).

I would be happy to provide any additional information deemed necessary.

The event logs in my router (C7800, hardware version V1.07, firmware version V3.01.38) shows nothing interesting. 

Here are the results of some ping targets (via PingPlotter Pro with a packet size of 56 bytes) over approximately the last 24 hours (I can share the data set and use other packet sizes if requested):
