The "in your vicinity" server filter does not display br servers.
They are kind of laggy now, probably because of the huge amount of players that must be playing in lower tier servers (can't see them with a tier4 acc.) now that this is the first day. Besides that, the connection is surprisingly good.
It's a community effort. I was just told id didn't and doesn't put a penny to upload the br servers.
unfortunately due to routing you probably first go to eu (de, uk etc) first. and then routing backtracks to turkey, resulting in massive ping.
this is due to your countries decision for international routing
