My company does technical support for a website that sells letterman jackets. This site doesn't do any SEO or anything since they were #1 for all their keywords for as long as I can remember. They were hosting with HostGator and there were A LOT of issues and downtime, so after the last major outage on Wednesday they've decided to move to SingleHop. We moved the site, everything's fine. Few days in - I get a note from Rankinity saying that they are nowhere to be found for ANY of their keywords. Even the site's name. I'm getting a major WTF moment, checking them manually and it's true - they are in fact nowhere in the first 100. Google Webmasters doesn't show any warnings or anything. WTF just happened? I might assume it has nothing to do with moving servers, but what are the proper steps in a situation like this?
