Hi MH,

This might be a long shot... but is it possible that you have enabled persistence? I'm not that experienced in DNS, but it does have a few quirks.

    Hello,

    Persistence is enabled, we can see in the log file that the processing of the DNS requests are selecting the correct IP based on persisntence, furing the normal operation of the service. In the failover situation, we can see that the selection is not using persistence to pick the answer. 

    Many thanks,

    Michael
