juju status reporting API server connection error while bringing up new state servers

As you can see from this paste:

$ ./juju bootstrap
$ ./juju ensure-availability
$ ./juju status

I run bootstrap, then ensure-availability.

After this step we "appear" to fail to connect to a local state server (despite being configured to use aws)

After sometime the extra state servers come up and we're back in our environment

Is this expected?
