I had purchased a domain from GoDaddy. After purchasing it I had set the nameservers to
ns1.epizy.com and ns2.epizy.com.
Later I changed it to ns1.freehosting.com and ns2.freehosting.com.
But when I open my URL it redirects me to old Hosting Provider. When I asked my old Hosting Provider they said something about 'Domain Propagation'. Could anyone help me. They even shared me the link - http://en.wikipedia.org/wiki/Domain_propagation . Please help me.
