Thank you for the reply; in one fell swoop, this explains what I encountered.

I would like to correct that, because it's not true. > In fact, there is no such description in the current version of the documentation (and there hasn't been for quite a few versions); as far as I can reconstruct it, I first encountered a description of a link between the cluster leader and a ClusterSingleton actor in version 2.1.4 of the documentation <http://doc.akka.io/docs/akka/2.1.4/contrib/cluster-singleton.html>. I've then also seen questions (and answers) on stackoverflow mentioning this connection. But newer versions of the documentation (at least 2.2.0 and later) mention only the oldest cluster node being linked to ClusterSingleton actors, just as you describe. I suspect that lingering remains of the v2.2.0 documentation page are perpetuated by search engines. ClusterSingleton run on the oldest node. > The leader is something that is mostly used by Akka Cluster itself to > manage the membership.

We have now started testing an implementation using information on the node age, and so far this does show the expected behaviour.
