In the current design, whenever one or more server goes down, or comes up,
there must be atleast one common server between the previous subset and the
new subset of servers, who can carry on the self-heal knowledge to the newly
added servers.

The future versions we plan to implement proactive selfheal where we record
deltas of changes, and this need should go.
