Creo q hay servidores en br, yo tengo 60-90 ms la mayoria de la veces.

Pero hay veces(muy pocas)q te manda a servers yankees y tenes 200 ms.

Aca dice como funciona el Matchmaking:
A second factor we take into account is ping. We’re matchmaking people all over the world and we want to match people to the closest servers for the best play experience. In our second stress test, we had other things prioritized over ping-based matchmaking such as skill and time. For those of you who participated in that stress test, you’ll remember how terrible the game performance was on the first day as well as how “lit up” the forums were demanding that players be given an option of server choice. So now we prioritize ping for players. Some players live in challenging parts of the world when it comes to high speed data connections (I’m looking at you, Andes mountain range…) so it’s not perfect for everyone. But largely, most people get a really decent connection to our game servers. Matching players with wildly disparate pings also results in a higher frequency of undesirable side effects such as “getting shot behind walls”. Of course if you live in Houston, Texas and group with your buddy in Geneva, Switzerland, you’re now introducing uncertainty to our system that’s harder for us to deal with… but we allow it.
