Matchmaking Latin America - No one is playing?


Hey Guys, just saying that now its almost impossible to play at mornings here in BRazil. Three days in a row, around 7 to 10 a.m. and the game just cant find one player to play with me. I wait for 5 to 10 minutes, reset the game, steam, the computer, but it doesn`t help.
Is it broken? Server maintenance, or no one is playing at this time?
