Does anybody know what is the best time of the day/week to start the propagation process of your domain so that most servers get your new DNS info as fast as possible? I heard that most servers in the U.S. get information about new DNS settings at around 5 p.m. EST. Is that true? Will it be better if I change the DNS settings at my registrar's web site (directnic) right before 5 p.m. EST? Assuming that sites are visited less on weekends, will it make sence to change the DNS info on Saturday rather than on any other day of the week?
