I have pointed my domain to the following DNS
But even after 3 days, the when i tried to visit the domain it says that the domain's server DNS address could not be found.
How much time does it take to update the DNS?
Please contact Godaddy Support and also cross-check your DNS
I get a server fail, so this points to your zone being incorrectly configured. Please recheck your DNS settings and use default. If your hosting is with another company just try forwarding your domain.
