Getting instance servers from the wrong region

Hello Guys,

In some of the zone I'm having ~100ms, but usually ~25ms.
After the 2. RIP because of a LAG I started digging deeper.

I'm playing on Frankfurt (EU) servers. (I wish to play)
But sometime the instance server is located in London. (E.q. 149.81.222.186)

Why is it happening, could you Fix it please GGG?

Can I change the server pool client side?
