Les,

I know the A record was on the old Nameserver because the website worked (including ping, etc...)?

On the new Nameserver (i.e. in the GoDaddy interface) I could see the A record and I didn't change anything when they did their "refresh". ?I after I changed GoDaddy's DNS records for the domain, their system didn't send out the right info to the Authoritative Server until I had them do the manual refresh. ?I don't think it was a propagation problem like they said.

I think my real questions are:
  1. When a DNS cache server needs to pull new records, does it pull individual record types like all the MX records but not the A records, or does it pull all the DNS records? ?(My theory is that it would pull all)
  2. If you change the Nameservers for a domain name is it fair to say that you would either get the old A records or the new ones and not have missing records? Since the new DNS info would replace the old, I don't see how the system would come back with a "missing" record, unless the new information sent to the Authoritative server was messed up.
Does that make sense?

Regards,
Eric

Dear Eric,

I would wonder what evidence you have that the new A record was ever
there? ?For example, maybe you entered it into a web form but forgot to
press the "save" button, or the save action was silently lost.


Best regards,

Lester
