gamaniagames loads an x10 hosted site when I try it.
DNS 'propagation' is uneven. People who have never tried your domain will go there quickly. Those who have gone to an old server will show the old info for awhile.
All depends on the register as well as the DNS servers and settings people visiting your site are using. For me, I can hit a DNS update almost immediately after a person applies an update to it. Others, yeah, may take up to 2 days to get the change.
