There appears to be a problem with Apple’s iCloud servers, with many users reporting that they are unable to access messages, Apple Music, files, and more. Posts on social media showed urgent problems with several iCloud services. For example, users reported that their iCloud account login status was kicked out, or that they were unable to access anything stored on iCloud servers.
Apple’s System Status page started reporting issues, and it can confirm that at least some iCloud services are slow or unusable, although this appears to be a localized problem. Some users can access certain services, such as viewing files stored on iCloud on one device but not on another.
This is what happens when your home goes all in on Apple products (iPhone, ipad, Mac, Apple TV etc) when iCloud goes down. Every device starts going off telling you to log in, just to go in a continual loop.

Some people have been able to access services like Apple Music on the iPhone, but not on the Mac. Show iCloud Backup, iCloud Mail and Photos are currently unavailable for some users. According to the support page, Apple may have been aware of the problem as early as 6:15 ET, although the error message was not registered on the system status page until 8:25 ET.
