A user equipment (UE) can experience a server-identifier failure, wherein a network fails to provide the UE with one or more server addresses required by the UE to access network services. To reduce the impact of such a server-identifier failure, the UE can maintain a local database of previously received server identifiers. In response to a server-identifier failure, the UE uses the database to identify and communicate with the corresponding server via the network. The UE is thereby able to access network services, such as DNS services or SMS services, in the event of a server-identifier failure, thereby improving the overall user experience with the UE.
