DNS Propagation To Start Within The Hour

I just got word from a technician at our hosting that he is currently in process of moving the account back to the previous server, and that the DNS propagagation should start "within the hour". This means that the server should be accessible to the people in North America in about 2 hours or a bit more, and the move should be completed world-wide in about 6 hours. I will keep posting the details.
