A system includes redundantly configured resources designated as active geo-redundant nodes (AGNs) and standby geo-redundant nodes (SGNs), a set of covered agents (CAs) that rely upon the redundantly configured resources, and a geographic redundancy coverage issuer (GRCI) configured to manage the geo-redundant nodes. The GRCI maintains a CA list identifying a set of subscribers to redundancy management services supported by the GRCI, an AGN list identifying a set of active geo-redundant nodes, and an SGN list identifying a set of standby geo-redundant nodes. The GRCI provides the AGN list and the SGN list to subscriber CAs. In response to receiving a message identifying a failed AGN, the GRCI updates the AGN list to reflect a failed status for the failed AGN and issues an update message to CAs reflecting the failed status for the failed AGN and a transition of an activated SGN to the AGN list. |
