Heres the problem:

When a I type:

domain.com > I get a new server (website uploaded to new server)
www.domain.com > I get old server (website uploaded to old server)

BUT...

When everyone else gets the new server info on using both www and no www.

The client has updated the DNS at godaddy and it's propagated correctly..

The thing is I'm sure everything correct because everybody gets the new site with "www" and without "www" EXCEPT me.

any help?

It might be your ISP's DNS cache... IMO

How would I go about fixing this?

Wait :) You could also try rebooting your local computer, as the caching could be occuring at your local DNS client level.

You can try to ping your domain with/without www prefixed. If both return the same IP, then it is your browser cache issue I believe.

Clear your browser cache and history. Reboot and ping again then start your browser to check.

If the ping return different IP which you believe your domain with/without www prefixed are both pointing to the same IP... then wait for your ISP DNS cache to refresh which normally might take from 24 hours to one week Or call your ISP for help.

Just my thoughts ;)

This sounds really stupid :S

How would I ping it?

Thanks

goto command line and type

ping www.domain.com
ping domain.com

Ok, when I ping each I get 2 different IPs and only 1 belongs to my server (the one that points to the new site).

this is where it gets really twisted...

Other people are getting the new site with and without the www.

What possibley could be happining?

Thanks

Your ISP nameservers have different entries for both www and non-www. It should resolve itself eventually. It is your ISP though it would seem. If you can't wait, you should call your ISP, but it will probably be quicker to just wait for them to refresh their records instead of jumping through a lot of hoops with your ISP.
