[Pdns-users] PDNS recursor cache sync

Just ran into an issue with recursive DNS servers where the two servers have cached a different A record for mirror.centos.org.
This is a problem as the firewalls permit access to the FQDN, which presumes that both the client and the firewall end up with the same A record for the domain.
I'm intending to swap these recursors out with PowerDNS servers, but am wondering if there's a way to keep the record cache in sync between multiple recursors.
