- As of June 2015, analytics102[345] which were Zookeeper servers in the Analytics Cluster have been moved out into the general purpose production network and renamed as conf100[123]. These are still Zookeeper servers, but will also host etcd.

- In August 2015, analytics10xx kafka brokers have been renamed to kafka10xx with the numbers (e.g. analytics1012 -> kafka1012).

- In October 2015, analytics1011,1016,1019 were repurposed as aqs1001,1002,1003.
