JAFF Index down?

Hello everyone!

After a long time, today I've tried to access the JAFF Index, to no avail. Before, the website used to load and then I could log in no problem. But now, even before loading, my browser asks me for user name and password. The problem is, despite typing them both, the website doesn't load anyway. I'm using a laptop with windows 10 and Firefox.

Can anyone help?
