1. A method comprises:

  • for a data access request, determining, by a device of devices of the dispersed storage network (DSN), when a DSN memory operation related to the data access request is at a critical juncture, wherein the data access request is regarding a set of encoded data slices that are stored or to be stored in a set of storage units of the DSN, wherein a data segment is dispersed storage error encoded to produce the set of encoded data slices, wherein a decode threshold number of encoded data slices of the set of encoded data slices is required to recover the data segment, wherein a write threshold number of encoded data slices of the set of encoded data slices is required for a successful write operation, wherein the critical juncture includes the DSN memory operation being within one of a first offset of the decode threshold number and a second offset of the write threshold number; and

    when the DSN memory operation is at the critical juncture;

    detecting, by one or more of the devices, an outstanding action with respect to the DSN memory operation;

    suspending, by the one or more of the devices, execution of non-critical DSN operations; and

    prioritizing, by the one or more of the devices, execution of the outstanding action.
