High packet loss on Comcast hop

I'm working with Cisco on troubleshooting some issues my organization is having with WebEx. I'm running Visual Traceroute to Cisco's destination address and one of the hops, AS7922 which belongs to Comcast, will always have a packet loss of 50-70%. Is this normal?

This turned out to be my modem and related to a PUMA 6 chip! Swapped modems with Technicolor and I was good.

Packet loss when pinging an intermediate node in a traceroute result is not unusual. And, in fact, is almost meaningless. The ping result of importance is the end-to-end packet loss which, in your example, is zero.

A more detailed response is in "Traceroute does not explain everything", https://forums.businesshelp.comcast.com/conversations/connectivity/traceroute-does-not-explain-everything/5fe0a62cc5375f08cd962a93
