I have not done anything wrong in terms of violating Google search policies. My site was offline for two years. I had moved the site from one hosting account to another and forgot to change the nameservers. I then suffered a period of ill health, quite severe, to the point I lost any motivation I had of running my sites. Thankfully, I have now recovered from those health issues and want to get back to managing the sites again. I fixed the server issue three or four days ago, but so far Google hasn't re-indexed the site. I submitted the home page to Bing after not getting indexed there after the first two days. They have now indexed the home page (though no other pages yet). The site itself has plenty of good back links (built naturally, without soliciting) and I used to get around 1000 uniques a day.
