CubeTube.org site dead?

After running the same animation for a looong time on my L3D cube (which runs a Photon), I thought I’d log in to cubetube.org and see if I can get a new animation. It looks like the login process is broken though - it’s supposed to use the same credentials as particle.io, but I click Log In and get no feedback at all.

Is anyone else with a cubetube account able to log in?
