Failover

[Mohammed Ejaz]

First of all many thanks for your response, 

Actually we are in ISP; this solution is for one of our customer in this
case we need to give the access of  the server to the customer,

This is not the DNS job to check at the web service availability.

You could make an external script that is testing for the service
availibility 

and change the dns accordingly, like (...) : 

 

web1 active  ?

    yes : was it active at last test ?

            yes : do nothing

            no : set www to point to web1 in DNS

    no : was it already inactive ?

            yes : do nothing

            no : set www to point to web2 in DNS

 

and with having www/web1/web2 having a low TTL.

Hi all, 

 

Can it be possible through the bind, www records should work as failover, I
mean during the primary record unavailable and then it should go for next
www only, Pls. note that I don't want let they work as round robin function.


 

1. Primary www record pointing 1.2.3.4 as long as it is available it should
read from the same IP, 

 

2. Secondary www record pointing 4.3.2.1 it should act only incase of
primary is down.
