The universe crashed due to the Voyager probe causing excessive chunk generation. Buffer overflow.
(In the new patch chunks not occupied by objects capable of sending data to logged-in players will not be loaded. A 27 chunk cube around the probe will remain loaded as long as it is sending.)
Since there isn't much to render out there, this shouldn't cause any update errors. We were able to cover up the issue, ironically, by making the probe appear to crash.
