This has happened to other sites as well. When you register a domain name, you don't get it "forever" you get it for three years (or maybe a bit more or less.) If you fail to renew in time, you get what happened to the Hartford page. Should Hartford renew in a timely manner, the page will magically reappear at that same address. Should they not renew, the name becomes available for someone else to use (Hartford Connecticut tourist catchkas?)
