Welcome to the Q&A Forum

I see your homepage is back in the index in Google when I do a site: search, and in google.com it's showing up on the first page for a search of Advertising agency Cambridge from California. Did you figure out what happened and why you got back in? Or just celebrating that the page is including again? Glad to see it's back in there!

Very in-depth response so thanks for this. I will see how quickly Google reindexes my proper site now that I have a redirect in place for that not so wanted domain. I will also send another 'calm' e-mail to the domain owner to see if I can get them to respond and point it away from my server. Thanks again!
