I mapped my domain last night but it still showed the under construction page. I read that it can take a while to map so I waited until this morning and sure enough, it showed up correctly. But now it’s back to the under construction page. Even when I use familycareconnection.wordpress.com it directs to familycareconnection.com with the under construction page.
If you do a forum search you will find threads where Staff and volunteers explain that there are many ISPs all over the world where DNS caches have to be flushed before the domain name change propagates throughout the internet. Many ISPs use invisible proxy servers (you typically never know they are there) and if they have some caching or updating issues on the invisible proxy servers takes time. Sometimes we see fluctuations back and forth.
