Apple reporting ongoing iCloud Mail and Notes outage for some users [Update]

[UPDATE: Apple’s system status page says the issues are now resolved after four hours.]

If you’re currently experiencing issues with iCloud Mail or Notes, then you’re not alone. Apple is currently reporting an ongoing iCloud outage affecting a small percentage of users (which is probably still a lot of people at Apple’s scale) when sending and receiving email with iCloud Mail or using iCloud Notes.
