I got the same problem myself.
I changed the hosting server yesterday and to do so I change the nameservers on godaddy.com.
It’s weird because on my computer my domain still points to my old server.
But on all other computers it seems to work right. I tested this using Browserstack (cross browser testing service).
I also cleared the browsing history and the DNS cache on my Mac.
It is really strange, because it seems that my entire network has got that problem, because my iPads have the same issue.
Is there a cache on the router itself ? Is the problem caused by godaddy?
@jshjohnson Do you have registered your domain as well on godaddy?
