I just updated the nameservers on an addon domain and over the last 12 hours, the domain has been totally inconsistent about which server will load when I refresh the page. This is from the same computer. One minute it's from the old server, then it's from the new one, then an hour later, the old one again.
Is this normal? Is this an indicator of a bad hosting company? Is there a way to force my computer to pick one or the other so I can continue a little work on the site until it is done resolving?
