Tokyo Server(s) Issue - Need help troubleshooting

Looking to pinpoint an issue I'm having with ISP/Apex Servers here in Japan. I have the UO Trace Utility, however I need the IP/domain name for the Apex server(s) out here.

Symptoms:
In game, ping will range from 10~30ms, all the way up to 110~130ms
Packet loss: 1%-15%

Always happens between 9/10pm - 12/1am. I understand "peak" times. However, I never had this issue until late December. I've changed nothing in my network configuration at home. Other players on same ISP in different locations here in Tokyo experience the same issue, which leads me to believe it could be my ISP. I need some help digging so I can at least bring the information to them if it indeed is my ISP.

What's weird is that when players start dying and quit the server, the ping and packet loss get lower. Tokyo1 seems to work best for us. Provides consistently low ping, however there's always some kind of loss. It's frustrating being that I have extremely high speed fiber. My speed tests show ~700-900Mbps down and ~900-1000Mbps up. I am aware speed doesn't always translate to quality of connection, just pointing out that bandwidth is not an issue.

@EA_Atic 
What time are you getting the issue- See above.
Who is your ISP- NURO光 (Provided by So-Net).
What platform are you on- PC (Steam, also tried on Origin).
What country are you in- See above.

I've provided some traces and polls as well. Tokyo1 is showing up as "unlisted" in the Apex server list (100 ping and -1 PL, can't connect to it...) but I can run a traceroute to it...
