is "gi1-3.ccr01.cmh02.atlas.cogentco.com" on wow's side? 20% loss on three cogent boxes in a row seems REALLY bad...

Maybe WOW_Dan can clarify this for us. Does the internal WOW network, which is shown here as addresses in the 10.0.0.x range, drop or prioritize packets? Or should we always expect an echo response to our echo requests when we use ping as a tool to measure latency and packet loss?

That would be a Cogent circuit, not us. When I get back to the office I will see what I can do about checking that circuit out, but it's out of our control, we would have to contact Cogent if we found an issue with it.

The first hop after your router is the CMTS, that hop will never respond to ICMP, which is why you always see a "No response from host" in line 1 or 2. The 10.x networks you see are WOW routers that route to the internet circuits. These routers can and do prioritize if need be. It's not often they're strained enough to need to drop or delay an ICMP request, but it does happen when traffic is heavy. ICMP requests such as ping and traceroute are prioritized very low on most networks, as to keep people who are pinging from slowing down someone trying to stream a video or something important.

Thank you Dan for the response. I will wait til Thursday or Friday to see if you are able to post a response saying if you found anything. Next week I will pursue getting a replacement modem from WoW. Something that I can swing buy and pick up from the local WOW shop here, or best to set up a tech appointment?

Thanks again!!

And just another report for good measure....I don't know if these actually help you guys, but this was taken Monday night starting at approximately 8:20p local time:
