testing propagation

If all of the delegation is done properly and has propagated to all of the 
gtld servers, then any problems with resolving the zone are most likely not 
propagation delays, but misconfigurations either on your end or theirs.  
Tools such as the open-source doc or commercial utilities such as Men & 
Mice's DNS Expert can help to point out any errors in zone data or 
delegation.  If you post your domain name on the list, as well as names of 
the ISPs/servers that cannot resolve your domain, list members are usually 
happy to do a little digging or other work to see if they can find any 
problems that may not be obvious at first glance.
