Is my outage inside or out?

[SBK]

I am assuming that ID 129695 is the agent since your your traceroute is almost identical to the hops we have for it.

The weird thing is that for some reason the IP 142.254.184.109 has been considered part of your network while definitely it is not.
I am overriding that hop to be part of the ISP network to be sure that next outages will be associated correctly but at the same time I am opening an internal ticket to check why this has happened to your agent

Thanks -- but what interpretation should I put on this? Is my issue with the cablemodem ..111.1 or with the Charter device 142.254.184.109 (or the link between?)

I was still redacting my answer and stumbled on the hops assignment...

The above image shows the outages recorded at your site and you can see that both 192.168.111.1 and 142.254.184.109 are identified as triggering the outage

My question is are these two IP the LAN and the WAN interface of you ISP router ?
Or the private one is your router and the public one is the ISP?

In any case, as I mentioned above the Affected network is wrong when the 142.254.184.109 is "responsible" of the outage

Now it seems better, as far as I can see

I also have an answer for this

If you take a look at the hops

you will see that exactly THAT hop 142.254.184.109 has no ASN number/org this is something that can happen when portion of networks were before owned by a different provider (same could happen when the same company is assigned different ASN like 20001 and 7843 both belonging to Charter Communications)

So thank you for highlighting this exception!

So, ..222.1 is the inside of my router, ..111.1 is the inside of my cablemodem. 142.254.184.109 ("int-1.sndgcaxt03m.netops.charter.com") is, I believe, the first piece of equipment not on my prem; definitely not my cablemodem's outside IP.

Then the first ISP hop is and must be 142.254.184.109 which is how it shows up now

FYI still sometimes showing their IP as internal:
