The last sentence...
And I just had a chat with one of their agents, and this is how it went:
Dani: Hi, my name is Dani. Welcome to Apple!
Dani: Right now we are going through a maintenance period, so you will not be able to access Mobileme. Please bear with us as we are going through the transition. You can check on the system status on when everything is back up and normal. Please accept my apologies for the inconvenience. There is no ETA on when it will be operational.

Me: Okay, thanks.
He knew what I was going to ask when I answered before he came on to my reason for being there "Inquiring about MobileMe downtime..."
He came up with a response right away. I think they have that macro in their clipboards and just Apple-Z it to the chat window.

O well, keep on waitin' and refreshing me.com (or not)
******
Dani: No worries, thank you for your time and patience.
