Thanks for all the replies.
We built a new site for a client, "honoringheroesjewelry.com" which is a valid domain, up for several months by another developer, who will soon change DNS pointer to DH. In preparation for our newly developed site being "the" site, I went to DH Domain Managment console & mistakenly added the fully hosted domain name "honoringheroes.com", which after a while of being prefixed with a clock, showed on my list of domains. When I clicked "visit", I was apalled to see someone elses page. Thus, my post asking for help.
Based on the several replies, I went back to the Domain Managment console & deleted it by clicking the "x". Again, thanks for all the replies, I am reassured that I did not actually affect someone elses site.
