GTM domain name answers
hi all, i'm trying to understand a little better the wonders of the DNS process and the GTMs place in it. When a local DNS server of a client sends a query to a pair (Active and secondary sites) of GTMs (Authoritative DNS) for a domain name, would typically both GTMs respond or only one in the pair?
If the local DNS expects two answers and only one GTM responds, for example, only the Active site GTM, how long will the local DNS wait before it no longer 'cares' about a response from the other GTM (ADNS)? Is there a standard timeout?
