more likely, it depends on which server it's on & whether or not it's affected by whatever glitch...
you have to realize, that, they have a complex site, that handles a heavy volume of traffic. Imagine having hundreds of thousands of drives hooked up to your computer & having them all sync'd up, having security, managing subscriptions, vs free accounts, vs non-members.
I'm not a FF fan, but, w/ my certain (limited) website managing/admin experience, I couldn't imagine the headaches they are having right now. It sucks, but, what can you do?
Just hope they get it resolved quick & make it up to their (paid) customers...
