iCloud services were disrupted for some users Wednesday, June 20, 2012. Apple's official status page? "Users may be unable to access iCloud services." Apple's email, Calendar, and iMessage and more were down during the outage.
Apple's iCloud glitches rarely affect all services at once, but the incident affected all service, including Photo Stream and later Mail and Notes.
iCloud has over 125 million registered users since its introduction in October 2011.
Apple's iCloud is great for backing up iPhone data, but so far it is a limited 'toy' because users can't see their photos. The service only serves as a reservoir for photos while they are moved from device to device.
Apple eliminated iDisk, which will be shut down at the end of this month. Apple's iCloud doesn't offer any way to store data files independently from an application -- so much for progress.
Apple's new slogan should be "Have it our way!"
