When your server goes down, you are temporarily out of the index until googlebot confirms that your server is dependable again - that's not a penalty. What you do is up to you, but if you are understanding the situation correctly I'd say a server change is the best idea. You can return a 503 status until the files are in their new home.

All I can say is the longer you wait the slower your recovery can be. a lot depends on your history, how frequently googlebot has been spidering and so on. If you can get back online stably in 48-72 hours, that would be best.
Think more like Google does - they don't want to give their users a poor experience. But they do want to give them the best sites they can. If Google decided your site should get lots of traffic, there's something here that they liked.
I suggest you communicate through the "Reconsideration Request" in your Webmaster Tools account as soon as you know you are online and stable again.
