I think I understand the confusion. Here is a link to the statement that blizzard put out as to why the servers are unreliable. Anything else you might see online is pretty likely incorrect. Whether or not you believe Blizzard is making this up completely is up to you. This is what they put out, and this is what I am going by because this is all I have to go by. People speculating online is not something I would suggest you pay any attention to.
