do the servers work properly? i couldt fight at all on the last 2 days, just mid battle crashes.

The servers work properly
it usually crashes sometime due to heavy traffic and it last for usually a couple of minutes
up to maximum 3 minutes
it will hurt u if it occurs during an important match which it usually does so
if u experience sever problems its probably your connection

like the above post said check to see if there your internet is intermittent during the times you play SM. Go play the game and right when the game stops see if the internet closes or something.
