Seems to be completely busted today and I can't even contact Apple because the email form on the Connect website is on the same system and trying to submit an email to contact support dies with errors just like everything else.
I can't access any of my apps and I can't even validate through XCode.
Apple's System Status page is outright lying about the services being available.
Hi there! Thank you all for reporting this issue. We are aware of the issue and we are investigating. Please see our System Status page for updates.
