If you see an iCloud maintenance message

While your account is undergoing maintenance, iCloud syncing will be paused. Syncing will resume when maintenance is complete.

If you see a message in your iCloud settings on your iPhone, iPad, Mac, or on iCloud.com that your account is undergoing standard maintenance:

• You won't be able to sign out or sign in to iCloud

• You won't be able to backup content to iCloud or sync it across your devices

• You won't be able to send or receive email or other sharing invitations using iCloud

All Apple services connected to iCloud may be affected for the duration of the account maintenance. Syncing will begin again once maintenance is complete.
