Described herein is a node of a telecommunications network configured to determine that a primary index for data repositories of the telecommunications network is operating in a fail-open mode and, in response, provide a request received by the node to substantially all data repositories referred to by the primary index. The node is further configured to receive a response from one of the data repositories and, based at least in part on the response, build a secondary index mapping data repositories to subscriber identifiers. When a further request is received by the node in fail-open mode, the node may refer to the secondary index first and, if the subscriber identifier from the further request is not present in the secondary index, provide the further request to substantially all data repositories referred to by the primary index.
