Many of Apple’s services are currently experiencing an outage, with Apple noting service outages for iCloud Backup, iCloud Drive, iCloud Notes, iCloud Storage Upgrades, and Photos on its system status page.
The issue is ongoing at approximately 10:13 a.m. Pacific time. Apple says that users may not be able to use these services during the interruption, so features such as iCloud Backup and iCloud photo storage may not work at this time.
It is unknown when these issues will be resolved, but we will update this article when everything is up and running again. Earlier today, services such as the App Store, Apple Music and iTunes Store also saw an outage that has been addressed since then.
Update: The problem has also spread to iCloud Storage, Calendar, Mail, Keychain and Bookmarks.
Update 2: According to Apple’s System Status page, all issues have now been resolved, and the Apple service is up and running again.
