Update: iCloud Mail is back up after the downtime.

The outage appears to have started within the last hour. Users are unable to access iCloud Mail both from iCloud.com and within the Mail application on macOS and iOS. For many users, their sent/received emails are missing altogether.

On iCloud.com, users are seeing a “Can’t load Mail.” message, With Apple saying “there was a problem loading the application. In the macOS Mail application, users see an error message as follows:

Apple’s system status webpage does not reflect any sort of outage for iCloud services and the company has yet to respond aside from a few uninformed tweets on its @AppleSupport Twitter account. Apple rarely addresses outages aside from its status website.

The server returned the error: The IMAP command “LOGIN” failed with the server error: Service temporarily unavailable.”

Is iCloud Mail down, or have I just changed and then forgotten my bloody password again?

@AppleSupport iCloud mail seems to be down (phone and web). Is it just me, or is there an outage?
