The Internet is diverse and large - and the Internet directory system, aka the DNS Infrastructure, supports the diversity and size. When we setup a new domain, the registrar frequently advises us to wait patiently, before continuing. Congrats on your new domain! Now, we suggest that you wait 24 - 48 hours for the new domain to propagate, before trying to publish to the domain. When we update a domain - and add or delete a single DNS address - we won't always get advice about waiting, from the registrar.
