x-box live problems?

I was able to log into xbox live this evening without it freezing, but my gameplay was still… out of wack. Only about 60% of my matches on mortal kombat worked. The rest of the time it went to a black screen, sat for about 30 seconds, then went back to the game. This has never happened before, until the past day or so.

I hope they get some sort of update pushed down, or something.
