Welcome to the Q&A Forum

Last week I decided to switch for a UK server to a US one at Hostgator since most of my visitors are from the US. About nine hours later 99% of my pages disappeared from google rankings, only a few non-relevant pages are at position 100-200. All decent (1000-2000 word) articles on specific topics, are gone. These pages were getting 2-3 minutes per user of readership and a low bounce rate, so I think they were pretty good quality. Does anyone think it's possible I got accidentally added on a blacklisted IP? Or why would something like this happen. Since then, I've tried switching back to the old IP for 3 days, that didn't work. Now I've filed a reinclusion request with the details. Has anyone had a similar experience? What can possibly cause this massive drop in rankings and traffic? Any help is much appreciated!
