Let’s say that I launch 3 identical servers, each of which is running a zero node and an alpha node for HA’s sake. Now, in the Dgraph docs under the “HA Cluster setup using Docker Swarm” section, I see that all of the alpha nodes are connecting to the **same** zero node since they are passed the following flag:

```
--zero=zero_1:5080
```

My question is: what would happen in the case that server running the `zero_1`

node becomes unavailable? Would the remaining alphas be able to find the other remaining zeros?

Also, would the remaining zeros be able to peer with each other? Because I also see that they are all passed this same flag:

```
--peer zero_1:5080
```

If they are able to do so, will there be interruption to any transactions that are coming in to the remaining alpha nodes?

Thanks for any help and clarification, I really appreciate it.
