Put up a static page with a video that shows how it works. Explain on that page that the HN hug of death took it down and ask people to give you their email so you can contact them when you're back up. Oh also, don't feel stupid about this. I've done dumber things, like not knowing what ulimit was for a few months while chasing down all sorts of other rabbits that lead to nowhere. Crashing because too many people want to use your software is the best problem you could ever wish to have.
