Now that the game is officially launched and most COD players already got their copy.
Chances are, you will have no problems connecting to players around this region.
Best time to play as mentioned by other members here is from 6pm till late.
In the day, connection might not be as good as chances of you being connected to
countries further away are more likely.
So, to enjoy a good MP experience, add as many people from the Players List above.
Log on from 6pm onwards. You'll sure to have a "bloody" good time.
