Repeatedly crashing

The whole raid crashed so many times we called it for the night.
Come on bliz get ur act together.
Will try again friday.
Bug description: We would be kicked from the raid and disconnected, about half the raid each disconnect wave. This happned about 7 to 10 times and we called it for the night.
Many many people on the server had the same problems.
Please give us an update on this asap.
