On the current (2018/02/17) nightlies, when setting up a cluster of five nodes, all running dgraph zero and alpha, some alpha nodes get stuck loading snapshots and return "server not ready" errors for requests indefinitely. In 20180217T143148.000-0600.zip, for instance, node n1 repeatedly tries to fetch a snapshot, but never succeeds:

This was fixed by 5563bd2. We are going to do a v1.0.4 release this week and the fix would be part of the release.
