A first charging data record (CDR) generating node can receive charging server information and available CDR storage information from a second CDR generating node. The first CDR generating node can detect that the charging server is unavailable to receive CDRs from the first CDR generating node. The first CDR generating node can also determine that a CDR storage area corresponding to the first CDR generating node should not be used to store additional CDRs. The first CDR generating node can also select the second CDR generating node for storing the additional CDRs that are generated by the first CDR generating node. The second CDR generating node can be selected based at least in part on the charging server information and the available CDR storage information. The first CDR generating node can cause at least one CDR to be sent to the second CDR generating node.
