thank you Mr Mohammed  
 can you please provide  more details about load balancer do you mean using the DNS as a loadbalancer for the two sites "two IP records" or adding  the two DNSs into LB so they have to work with one virtual IP ? and for each questions , why and how :D  ?

Hello SdNOGgers hope you are doing grate ^_^ 
my question is about DNS fail over , i have DR site and want to make a DNS failover but from reading, it seems like DNS failover is not recommended , due to some considerations like  TTL  , and update time so what are the better solutions to achieve failover between two different data centers ? what if i want the DR site  to be reached via my original IP addresses, or via a different  IP address ? 

best regards
