It can take up to 72 hours from when we change the DNS settings. I changed them last night at 9:30ish.
Hopefully your ISP will update tonight at or close to midnight. If they do then your set. If not then it might be sometime over the night tonight. Or sometime tommorow.
At this point its all up to how often your ISP or even your ISP's ISP updates their DNS tables. For those who are not fimular with what DNS is I can explain.
Every computer on the internet has a number address assigned to it. For example one computer might be 220.127.116.11. Well we cant remember numbers very well but we can remember words. So there is a system that allows us to use words to assocated to a computers number. for example www.mywebsite.com
might equil the number of the computer above. If you move your site to a new computer the number changes. So you have to change the entry in the DNS to reflect this.
There is no 1 central DNS location for the world so there are thousands of DNS servers serving all the internet users. It takes 1-3 days for the changes to make their way around the world.
