Sudden Lag & Packet Loss

[Joker119]

I think some of us here are experiencing different issues.
I also have frontier, but am only experiencing this issue with FFXIV. There's a bunch of packet loss when the connection moves over to the NTT servers on the route to SE servers.
Outside of XIV servers, I have 0 issues with ping/packet loss/connection speed anywhere else.

Using my phones hotspot also does not resolve the issue, as it's connection is still routed through NTT.

Using a different ISP (my neighbor's wifi using comcast) also has the exact same behavior.

Also connecting to my VPN server does not resolve the issue, as it's still routed through the affected NTT servers in cali. (VPN is located in Las Vegas)

It's basically this issue, https://forum.square-enix.com/ffxiv/...NA-Data-Center
which has been stale for 4 years, but seems to have come back very recently (it's only been noticable the last 3-4 days for me).
