Did anyone else's site just 'drop out' of google listings today?

Yesterday we're ranked high in most of our relevant keywords, then
today we're completely gone. There were no changes on our site for the
past week or so, and only minor changes to products pages then.

Even searching the url directly results in:
Sorry, no information is available for the URL www.appliedmembranes.com

I have re-submitted my site for indexing, and beleive this is all I can
do.
I just want to know how many others this is happening to.

(or if anyone has any ideas for me, that would be great too)

Thanks!
