Specifically they pushed the problem to the load-balancer so they get to check this one too. (x) your solution requires a central authority that cannot be unavailable I'm amazed the author doesn't consider that the load-balancers in this situation are effectively acting as non-voting witnesses and that the whole system hinges on the lbs being able to correctly determine the healthy nodes. In a single-master setup the network partition that cuts the line between the lbs and the current master (but nothing else) is a fun one. Everything would be fine if you could promote a new master but who's gonna tell em'?
