If this morning you could not access the services iCloud Photo Stream, Documents in the Cloud si Backup, then I'll tell you that Apple company's servers they have some problems of functionality. Just a few tens of minutes ago, most of the iCloud services were non-functional, but at the moment only the 3 previously listed still generate problems for users. You may encounter problems if you try to make a backup with iCloud or restore it, if you try to view photos from Photo Stream, or if you try to synchronize documents with iCloud.
