servers crashing

I'm not sure if this has been brought up but in the past month or two the BF3 Conquest server has been crashing frequently. Sometimes, the server will crash multiple times in a round and it is usual to see this several times a night. It is bad enough that I just stop trying to rejoin...

Does anyone know whats up with the server problems the last couple days? Strange major lag at times, servers crashing, that sort of thing. thanks
