A method includes maintaining, by a storage unit, a plurality of source name based addressing maps regarding encoding data slice storage by a plurality of storage units. The method further includes receiving, by the storage unit, an access request for an encoded data slice having a source name corresponding to a DSN address. The method further includes accessing, by the storage unit, the source name based address maps to determine whether the encoded data slice is effected by the DAP redistribution operation. The method further includes, when the encoded data slice is effected by the DAP redistribution operation, determining, by the storage unit, to execute the access request, proxy the access request, or deny the access request. The method further includes, when the determination is to execute the access request, executing, by the storage unit, the access request for the encoded data slice.
