I'm a 1%er and it's been a week for me. Mail worked at launch and then last email I received was last Thursday.
So now, the question is Apple, at what point do you throw in the towel, replace the stinkin' sever and just tell us that we're hosed but at least you have email again. What I'm really not liking is the lack of updates. That support doc was last updated (3) days ago. I mean, at least keep it updated...even if you have nothing new to update. Then at least I feel like you're working on the problem!
