  Oh, I love it -- a disaster caused by "disaster recovery configuration" :-) People install failover configurations to minimise time-to-repair or time-to-resume service (and some customers' contracts will demand this). This is at the expense of another layer of stuff to go wrong, and raising the possibility that it fails over when it shouldn't, causing brief but embarrassing outages. It's possible in some such situations that, on the balance of probabilities, introducing mechanisms like this cause more disruption over time than they were intended to protect against, and that this is more widespread than often considered. Still, their operational cost must be borne in order to satisfy the clause in the customers' contracts.
