DNS-based Failover solutions suffer from the same limitations as DNS-based Load Balancing solutions. However, in disaster recovery scenarios, the effects of the inherent latency of DNS-based solutions are even more severe—markedly lengthening RTO (Recovery Time Objective, or the amount of time a business can function without the system’s availability).
