Apple is reporting that services for some iCloud Mail and Notes accounts may be down.
It looks like this began shortly after 08:00EST and is only affecting a small percentage of users. However, when your as big as Apple, 0.86% adds up, and people are taking to Twitter and other social media sites:
Mrs. Trellis - @MrsTrellis

Josh Lassen - @joshlassen
"iCloud mail has been down for 2 hours now, and I have emails I REALLY need to read"
John Hood - @johnhood
"Hey @AppleSupport, iCloud has been down most of the afternoon. Can't access email..."
