said by Anonymous_: It's obviously not the modem since the issue is at the 3rd hop.
"72.129.26.177" jumps from 300 to 400ms at night upto 1,000 ms "jitter" to the east coast.
seems to be happening in the day time now as well.

Trace complete.
Your pings seem fine on TWC's end. Don't let a few high pings earlier in the route fool you. Many routers deprioritize pings and trace routes to focus on their main job(routing) and to help protect against DDoS attacks via ICMP. Your ping looks good on the first Level3 routers, which is out of TWC's network. That being said, your ping to dslr is kinda crappy. Seeing the averages and ignoring the spikes(you can't have 60ms pings to level3 without TWC forwarding the packets to them that quickly), level3 seems to be your issue. There have been many complaints on this forum about them. Unfortunately, yours and TWC's hands are likely tied behind your backs. Sorry to say...
