iCloud iCloud issues right now — can't sign in on macOS or iCloud.com

[BenjipNZ]

Is anyone else having major iCloud issues right now? My Mac (running the latest Sequoia Public Beta) wants me to "Update Apple Account Settings" in the System Settings app, but attempting to do so just gives me either a small modal window saying something about loading, or just a blank greyed-out screen. This means all of my iCloud calendars are not sync'ing. iMessage seems fine.

I also can't sign in to iCloud.com. The Apple System Status page shows current issues for Mail and iCloud.com, so hopefully it's not just me?

On iPhone, my iCloud settings are a bit all over the place, looks like it's having trouble loading most of the settings within that section.

Apple services has been experiencing outages throughout the day. It started with iCloud mail and web apps... could affect more.

Yes, I am too! iCloud.com from my PC (in Australia) - the sign-in panel flashes up then vanishes, and the message "iCloud encountered an error while trying to connect to the server." appears.

Edit: have been using Firefox (latest version). I tried with the Chrome browser and could log in as normal! So perhaps it is a Firefox-specific issue? I tried clearing history and cookies, but no luck yet.
