I had a page on one of my websites that got a ton of traffic. The page was offline due to something I screwed up. Google noticed this and it stopped showing up in search results. The page is back online now, but Google hasn't noticed this yet. I have a sitemap and I submit it to Google, but it still shows up as "not found" in Google's webmaster tools. Will Google eventually figure this out? Or do I need to do anything else?
