A method for execution by one or more computing devices of a dispersed storage network (DSN), the method comprises: determining a root cause for a rebuilding request of an encoded data slice of a set of encoded data slices, wherein the rebuilding request includes a slice name of the encoded data slice corresponding to a slice error; establishing a pricing level as a user pricing level when the root cause is a user-centric root cause; establishing the pricing level as a non-user pricing level when the root cause is a non-user-centric root cause; facilitating the rebuilding of the encoded data slice; and generating billing information for the rebuilding based on the pricing level.
