What is wrong with your Network?

I play on normal ps5 with 500 Mps Fiberglas connection. Always around 10 in the evening my ping starts jumping from 10 ms to 250ms and more. Makes playing not enjoyable. No matter which Server i use (normally i use Frankfurt/Germany). This Problem is there since 0.1. The 0.3 makes it whorse, since more happens onscreen. Friend of me owns ps5 pro and got the same problems. So when will u fix your network code???

Agreed, I have the same problem at times.
