Frequent and High Latency Spikes

As the title says. Since moving into my new living situation about 6 months ago, my latency in Path of Exile specifically has consistently been awful. It seems to be on an instance by instance basis, with some zones being fine and others unbearable. Switching to any other game when ping issues arise seems to indicate that this is isolated to PoE, as nothing else matches the latency spikes.

Doing some googling wasn't able to produce any solution, I tried connecting from a VPN (nordvpn) and the latency seems to stabilize but is on average twice as high as normal (~60ms -> 120ms) which isn't ideal.

So now I'm here, I've followed the instructions as per https://www.pathofexile.com/forum/view-thread/1377789 on running a winmtr trace to get a report, I'll share three different traces from three different instances below.

Is there any way to resolve these issues and get my latency back to a tolerable state?

It's probably still something related to your setup, as the game works fine for everyone else.
Could be your internet service provider, or may as well be something unstable about your PC.
I would suggest to disable any overclock, especially if you're on an Intel CPU and test again.

I don't overclock. I don't think this is a hardware issue, I've gone through probably the first 5 pages of google results of "improve your PoE performance with these 5 hacks" despite most of them not understanding the difference between latency and fps. This includes: basically any permutation of in-game settings including renderer, "optimize performance" options through my nvidia control panel, flushdns through the terminal, and many more. I understand these are almost all fps fixes and my issue is ping, but I tried them anyways because why not.

I'm not claiming that the settlers necro league is the cause of my issues, this has been a problem for me for the past 6 months.

There is quite a record of this issue throughout the forums but largely the answer boils down to "it seems like you're routing through bad nodes" with no further solution. I'm posting this now because I'm guessing I fall into that boat, but I don't have the expertise to confirm that. And if that is the problem I'm experiencing, I don't know how to resolve it.

Call Spectrum

All 3 of those WinMtR's have packet loss right after your router. There is a problem between your modem and their hub.

To add to that, do a full power cycle reset of your modem/router first.
