iCloud Mail has been experiencing an issue over the past few hours and is currently down for some users, according to Apple's system status page.
There have been a number of reports on Twitter and from MacRumors readers over the past few hours, although the volume of reports doesn't seem terribly high, so the issue may be affecting only a relatively small percentage of users.
User reports indicate iCloud is having problems since 7:56 PM EDT. https://t.co/cMx6KRH6gt RT if you're also having problems #iClouddown — Downdetector (@downdetector) November 1, 2022
Apple says the iCloud Mail service may be "slow or unavailable," but no other iCloud services are currently listed as affected.
Update 1:05 a.m.: Apple says the issue has been fixed after more than nine hours.
