cockroach lib logs
The node I was connected to is node 24 of the cluster davidh-large-console-test, which is definitely not ricky-test.
I think the cluster ricky-test was deleted by the time I tried to SSH in, though I don't know why it would have chosen a completely different node/cluster and silently connected me.
