Revalidating session data could be a smaller surface area than validating a fresh login. But if logging in existing devices works in some cases, and doesn't in others, the failure case is more complex than just fresh logins don't work.
Ah, yes, my original comment was a little unclear. I actually wasn’t logging in on new device vs existing device, it was that I had logged in to one device before 9:30est (presumably before the surge began) and just had an existing already-logged-in-session.
