How long does it take to replicate the DNS? I have a site hosted in Brazil and has over 6 hours that ran the exchange for Winhost. It will take much yet?
If you're talking about how long it takes for changes to your name servers to propagate, that depends on the ISP. Some refresh DNS every few minutes, some every few hours, some less often. In the old days we always used to say 24 to 72 hours. Though it rarely takes that long anymore. But however long it takes has nothing to do with us. The DNS for you domain is active the minute you set it up. If you're still seeing the domain pointing to old name server information, your ISP is likely caching that information. It should clear up soon.
