Certain Instances cause constant lag spikes

Hello!

I had this issue since around 3.22, to where I eventually stop playing really early because the lag is getting really obnoxious for me. The problem is, it's kind of based on the individual instance. Sometimes I open a new instance for an area and that kind of fixes it. But it's extra bad currently.

Gateways: Milan and Amsterdam are about equally bad. I am in Frankfurt, but the Frankfurt Gateway is unusable.

MTR Results for a problematic instance are here:

Thanks in Advance if it can be helped at all!
