Public DNS Failover Options
Posted on 2011-09-02
I have a situation and not sure if there is a true solution to this.
Basically we have got to offices that are connected together via a 1GB Fibre line.
In each office is a 100mb internet line, and if office a internet goes down it routes via office b and vice versa.
So we have an a record called webmail.company.com and this resolves to an ip in office a, and when that internet goes down webmail becomes accessible.
Is there a 3rd party hosted dns sevice which can repoint this if a host becomes unaccessible?
