1. A method, by one or more computing devices, comprising:
accessing a cluster of computing nodes of one or more clusters of computing nodes executing on an edge site computing network, wherein the cluster of computing nodes comprises a plurality of follower computing nodes and at least one leader computing node;
detecting an interruption to connectivity established between the at least one leader computing node and one or more of the plurality of follower computing nodes;
in response to detecting the interruption to connectivity established between the at least one leader computing node and one or more of the plurality of follower computing nodes within a same cluster, and while connectivity is established between the one or more of the plurality of follower computing nodes and one or more other computing nodes of the plurality of follower nodes within the same cluster, bifurcating the cluster of computing nodes into a first subcluster of computing nodes and a second subcluster of computing nodes; and
in response to detecting a restoration of connectivity with respect to one or more computing nodes associated with the first subcluster of computing nodes and the second subcluster of computing nodes, recombining the first subcluster of computing nodes and the second subcluster of computing nodes.
