[SEEMS SOLVED] Network latency shoots up, disconnected from instance every 5 mins

Since the new league launched, I've been getting consistent disconnects from the instance servers every ~5 mins, except for an extended period last night when everything worked fine.

Here is the MTR results of a test just now, capturing the moment I was booted back to the login menu:

Attempted fixes from my end:
Selecting NZ gateway (Im in Australia)
Rebooting all of my networking equipment
Disabling my PiHole
Rebooting my PC
Checking for Windows updates (none available)
Checking for motherboard/NIC updates (none available)

I don't get these disconnects in any other game (Battlefield 6, PoE 2), and I can't see many other people complaining about server issues, so I believe this is something on my end, but I'm not sure what else to try to troubleshoot the issue.

Nothing was different with the gameplay that worked fine last night, other than perhaps time of day.

What had you entered into WinMTR's Host: field?

I don't think it's on your end, people have been complaining a lot on Reddit about instance crashes and ping spikes since 3.27.

I'm experiencing the same issue, instance crashes every 5 minutes it's completely unplayable... T_T
