I once accidentally unpublished my book from Amazon. Yes, another facepalm moment 
However, while it was offline from my account 'bookshelf' for about 24hours, it didn't actually disappear from the site at all. I didn't try to buy it, but I presume that unpublishing isn't an instant takedown. The actual book page that people see stayed the same--there was no message that said "this title is unavailable in your territory", and it also didn't have the Amazon message about unavailable pricing information.
I don't whether my account is glitchy, or whether everyone who unpublishes has to wait a while for their books to go offline.
I also can't remember what the status bar said during that 24hours.
Hope that helps.
