    10  
    11  [Consul Enterprise](https://www.hashicorp.com/consul.html) [redundancy
    12  zones](/docs/guides/autopilot.html#redundancy-zones) make
    13  it possible to have more servers than availability zones. For example, in an
    14  environment with three availability zones it's now possible to run one voter and
    15  one non-voter in each availability zone, for a total of six servers. If an
    16  availability zone is completely lost, only one voter will be lost, so the
    17  cluster remains available. If a voter is lost in an availability zone, Autopilot
    18  will promote the non-voter to voter automatically, putting the hot standby
    19  server into service quickly.
