I just moved one of my sites to a new host, and updated the nameservers. When I go to the site without www, it goes to the new host, but when I browse to it with the www, it goes to the old host. How do I make the www goes to the new host?
DNS Caching, don't try to fight it.
This can also occur if someone forgot that the domain is still in its HOST file...
Be patient. As KuJoe said, it's the caches >.>
Ok, cool. It's working now
I hate DNS caching, it causes me sooooo many support tickets. Seriously, at least 75% of all support tickets are because "my site won't load" 15 minutes after updating the nameserver. I should create a page with a nice diagram I found of the DNS "web".
