Is Area51 login broken?

Is Area51 login broken? I tried to sign up today and this happened:

error message below

Unable to log in with your OpenID provider:

An unexpected error occurred while logging in. It's not you, it's us. This is our fault.
Detailed information about this error has automatically been recorded and we have been notified.

To clarify, this is happening as soon as I click either the sign up or the log in buttons.
I never get asked if I want to log in with OpenID (I don't; I don't even have an OpenID), nor do I have any other way of influencing the outcome.
