I added my domain ( lets call it foo.com ) to dreamhost, and the subdomain bar too it. Dreamhost is not actually the authoritative name server for this domain. However, I thought that although the domain won't resolve for this subdomain I created on dreamhost from the outside, I thought it would resolve on dreamhost's own servers.
When I query ns1.dreamhost.com for the subdomain it does resolve, but the dreamhost servers seem to use these cache servers like ns-cache01.sd.dreamhost.com . Will these cache servers eventually be updated from ns1.dreamhost.com, or will they always use the true name server that is set up for the domain?
