Question on servers?

Hopefully I haven’t posted this in wrong section.
I have a question on servers.
Specifically, I live in Australia and I assume that I am playing on Australian servers because thats all the people I’ve heard so far (maybe with a few Kiwis thrown in for good measure).
If this is the case, I was wondering if there was/will be a process of swapping servers. I’m only asking this because sometimes I work shift (or cant sleep) and jump on looking for a warzone game about 3am local time. At that time I cant find a match to save my life. I’m a bit worried that if/when the player numbers fall off, I will never be able to find a game.

Man this would be awesome if they added a server switch feature! Great idea!!

I am in nz and the last few games has been with a ton of us players
