Greetings PDNS,
Iam planning on a DNS environment composed of several servers with PDNS.
But have some specific scenarios I would like somebody to advise on how
client resolvers out there would most likely react.
a.) Suppose I have a domain name example.org it is hosted under the
nameservers: ns1.dns.com and ns2.dns.com. Suddenly ns1.dns.com starts
lagging severly (not down) / or is completely down. How well do
resolvers coop with this? Do they query both at the same time , or
randomly choose and wait ? If so how much would they wait usually?
b.) Same scenario as above but this time ns2.dns.com is misconfigured or
the zone for example.org is erased giving a non existing domain or
another possible error along that line. Would resolvers try to query the
second nameserver and try?
Thanks for the help.
Alex
