This only tests inside of COX, the issue is with the interconnections. Something changed on the handoffs, in particular with XO. Were there any changes in the last few months that removed connections in San Diego? Also I don't know how the system is programmed on the traffic shaping but I can NEVER get 16Mbps up ever. I just tried to upload a 700MB file and it capped at 5Mbps. That I can live with, but please let me know about the XO handoff and what changed. Thanks, Rich.

Can you post a tracert to show this change? Routing is dictated by a lot of things and can't be changed for a single user.

So you can see, we are going to Cox SD -> Cox San Jose and then via Level 3. I would still like to know what happened to

the direct connect to XO. And yes having helped start fund and operate 3 Internet Service Providers in

the last 30 years I fully understand routing can't be changed just for me. I would just like to know what did change

and why the previous connection no longer exists. Reverse traceroute shows the same path via San Jose.

Maybe a Moderator might be able to say, but I some how doubt it. You would need to get on contact with one of the local engineers.

Is this a normal cable modem connection or something Cox Business? The first hop confuses me. 

Maybe one will chime in if they know what happened with the connection. The first hop is internal to my

network so you can ignore that and the second hop is hitting my firewall which will not respond so it can

be ignored also. Running through the historical BGP table entries to see if I can pinpoint the day of the change.
