Getting some T3 time outs and a bit of packet loss

Nothing too bad but just to log that I'm getting a bit of packet loss from pings and by BQM look at Wireshark for BQM I have determined its loss on the upstream.

Those upstream channels are within the Digital TV bands, so it’s probably noise ingress. Someone on your street cabinet using their own bad coax possibly.
