Simulated DC failure is more often then not just traffic flow engineering. It is more about testing the DC that takes over the traffic than it is about testing service restart in the inactive DC.

There is little to test about the introduction of a hard fault, but the service resumption in the other DC is full of data to analyze. Also, in such a setup, getting the fault location running again is not on a hard clock, since it is about restoring redundancy instead of the service.
