I added a sub-domain to my main already active domain name, so that I could test a new web site before transferring the DNS info to make it live.
E.g. testdomain.mysite.com, where www.mysite.com is already up and running.
When I created the "testdomain" sub-domain using the DH panel, it told me it would take 2 days for the DNS records to be updated.
My question, is this accurate, or is it simply a reflection of the sub-domain and full-domain pages using the same "conclusion page" text when you complete the process using the DH panel.
More to the point, is the addition of a sub-domain made internally at DH (in which case it would likely be completed in minutes or hours) or must it be propagated through the DNS registries the same way a full-domain must (which would takes days?)
Thanks. Just trying to plan appropriately for this and future projects in terms of how much turn around time is required when setting these test sites up.
