The only thing I can think of is if you have an extremely high change rate on the zone, and can't afford to have the signer down for a few hours overnight if it fails. For pretty much any other use case you're fine having a single signer, with a much MUCH simpler configuration, which can be replaced in a heartbeat next-business-day if the production signer fails for some reason.</div><div><br></div></div></div>
