1. A method of accessing data in a dispersed storage network, the dispersed storage network including a plurality of dispersed storage units, the method comprising: dispersed storage error encoding a data segment to produce a set of encoded data slices; sending a first slice write request for receipt by a first dispersed storage unit of the plurality of dispersed storage units, the first slice write request including a first slice name corresponding to the first dispersed storage unit and a first data slice of the set of encoded data slices, wherein the first data slice includes a first information dispersed algorithm index of the first dispersed storage unit; and sending a second slice write request for receipt by a third dispersed storage unit of the plurality of dispersed storage units when a second dispersed storage unit of the plurality of dispersed storage units is unavailable, the second slice write request including a second slice name corresponding to the third dispersed storage unit and a second data slice of the set of encoded data slices, wherein the second data slice includes a second information dispersed algorithm index of the second dispersed storage unit.
