I'm having this issue very recently, I asked my friends (who lived in the US) and they never encountered any issues. I've received major lag spikes during combat and soon booted either 90002 or 90006 issue, it's getting to the point of being extremely frustrating not enjoying Patch 3.3's content. I have tried changed my DNS, my router and reset my PS4 connection and it had no effect. I would appreciate an update from anyone who plays this same in my country (Australia).
