Abstract
Technologies are provided for detecting backup network paths in a computer network using geospatial data. Geospatial data for network links in a computer network can be used to identify network links that are located within a specified distance to one another. Network links located within the specified distance to one another can be considered to share the same or similar risks of failure. Network links located within the specified distance to one another can be included in shared risk resource groups (SRRGs), such as shared risk link groups (SRLGs). The SRRGs can be used to identify a backup path for a network path that does not include any network links that are in SRRGs that also contain network links in the network path. The backup path can be used to transmit data if a failure is detected in one or more links in the network path.
