Jittery and extremely poor network stability

In maps, I get extremely poor stability with latency, and it spikes wildly between 4ms to several hundred continuously. I usually swap from the Singapore gateway to the Japan gateway in the past, but now, both have this issue.

Attempting to alleviate the issue with Predictive networking just results in being kicked for too many actions, even when I'm just holding down movement.

For some reason, this only occurs in the evening, after 7pm GMT+8. It tends to be smooth before then, but it's essentially daily.

The WinMTR results are below for the Singapore gateway:

Edit: I've tried using Mudfish, but it straight up just doesn't work, it just fails to enter any map instance. (Campaign zones are fine for some reason.)

can confirm im having the same issue, my fried also said he has this problem. Occurred yesterday aswell around the same time. pls fix

It happens every single evening in exactly same time =_= Similar issues on Frankfurt, London, Moscow realms, nothing helps.

It has to be specific servers or something. Ton of us on console having the same type of issues, we just have no way of troubleshooting so our fate is completely on ggg

The poor latency is still going on, at basically the same timings. Here is another report: https://pastebin.com/LTmzL3gK

Same here, game is unplayeble for two evenings in a row

It's still happening every single day on schedule. I'm not really sure what I can do here. I reset my router multiple times, but I'm unsure if it's the problem. Can't be excess load, surely, it doesn't start lagging until the same timings even on weekends.
