The boards are fixed!!! Maybe it's true this time.

Today on the Horizons site, David Allen of AE posted this message:

    Hi everyone, our new web server is ready. This will fix the slow connections, and the “you are not authorized” errors. Since we’re moving servers, we have to turn the boards off. We’ll turn them on again as soon as I’m done moving them over. It should take around 12 hours, hopefully less.
    Again, sorry for the inconvenience.
