Monitoring the health status of a distributed storage network (DSN) and scheduling maintenance tasks relating to identified memory failures. In various examples, monitoring the health status of the DSN can include obtaining status information regarding storage units of the DSN and, based thereon, determining that memory of one or more of the storage units requires repair. Physical locations for identified storage units are determined, as well as the level of data loss risk associated with encoded data stored in the storage units. Based on this information, a repair plan is generated for and issued to the identified storage units. A repair plan may include, for example, an ordered list of maintenance tasks that are prioritized to balance data loss risk considerations with repair effort efficiency considerations. The maintenance tasks may be mapped to available service operators for performing the desired repairs (e.g., based on physical locations of the storage units).
