Hi Community,
Thanks for the info everyone. The ping commands didn't end up providing any more useful info and the diagnosis is still the same as I described in my most recent posts. According to our IT team, if you contact Cablevision and give them the trace route, it will demonstrate to them that the problem lies with the lightpath.net hop and should let them know what needs to be addressed.
Our IT team does not feel the results of the ping command will help so there's no need to give them that unless they specifically request it. I will update this thread as I learn more, but there's not really much more we can do at this point.
