Abstract: Systems, devices, and techniques are disclosed for maintaining service availability. Files including code written using a Domain Specific Language (DSL) for network security may be received. A knowledge graph including connections between services may be generated from the code written using the DSL in the files. A service that will have an availability issue may be determined based on the connections between services in the knowledge graph. The service that will have the availability issue may be replicated. The replication of the service that will have the availability issue may occur before the service has the availability issue.
