I recently changed the domain of my site from a free sub-domain to a top-level domain. I used 301 re-directs to direct my previous URL's to the new one. For a couple of days my previous URL was listed in Google, with one of them listing the new url. Since two days ago, none of my url's are listed in Google at all. Could this be due to my site being in the sandbox, or something like that? My traffic has almost died seeing as I was listed in the top 5 for most of my keywords. Will this change, and how long can I expect this to last?
