I'm getting that glitch. It seems that if you sit on a page for about 5-10 seconds, it will randomly vanish. This will need to be brought to everypony's attention.
We're investigating as we speak. We'll keep you posted as information becomes available.
I'm also inclined to believe your credentials are safe for the time being.
I'm looking into both of the issues right now, but it is too early to say what's causing this. I'll be trying to contact out host to see if anything could have happened that way. It doesn't look like any accounts have been breached.
For reference, iirc, discouraged mode only feigns network issues, like load times and 404s and such. It shouldn't actually be able to make your page implode.
