1. A system, comprising: one or more processors; and memory including executable instructions that, as a result of execution by the one or more processors, cause a computer system to at least: represent a network of a plurality of cryptographic key servers with a graph representation comprising a plurality of vertices and a plurality of edges configured in accordance with one or more connectivity constraints, each vertex of the plurality of vertices representing a corresponding cryptographic key server, each edge of the plurality of edges connecting a pair of vertices of the plurality of vertices and representing connectivity between a pair of corresponding cryptographic key servers; respond to a cryptographic key event by traversing the graph representation to identify one or more of the plurality of cryptographic key servers upon which to perform one or more operations associated with the cryptographic key event; and perform the one or more operations associated with the cryptographic key event on the identified one or more of the plurality of cryptographic key servers.
