Hi leroydouglas,
The screenshot is from the browser's console on https://account.apple.com/sign-in. It shows an internal server error (503, with an apparent CORS issue) when trying to log in.
However, I can log in just fine on this subdomain, discussions.apple.com, which indicates that my system and account are not affected in any way.
The last two rows of errors on that screenshot are thrown after I input the code; which keeps me from signing in and gets me stuck there forever as you can see on the blank space on the left of my screenshot with a loader spinning till infinity.
Due to this I'm certain this issue lies on apple's side; specifically something with the account.apple.com subdomain's page.
