From reading, it seems like DNS failover is not recommended just because DNS wasn't designed for it. But if you have two webservers on different subnets hosting redundant content, what other methods are there to ensure that all traffic gets routed to the live server if one server goes down?
To me it seems like DNS failover is the only failover option here, but the consensus is it's not a good option. Yet services like DNSmadeeasy.com provide it, so there must be merit to it. Any comments?
