All hubs restart at once - can't join network for a brief window

All 3 Java hubs restart at the exact same time. If you try to join the network during this time (roughly a 30 sec window I think?), you can't join, likely due to there being no hubs available to send you to. If the hub reset times were staggered, that might solve this issue as then there would always be at least one hub available. Not sure if this would be considered a bug, but making note of this.
