[Pdns-users] Re: Mysql based supermaster to bind based slave?

[Max Clark]

Hi all,

I am just curious if anyone on the list has any comments on this. I
don't feel like I am being overly paranoid here - database failure are
few and far between but if the DB goes away not serving DNS records is
a bad thing. What is the general thoughts on this?

Thanks,
Max
