1. A method for managing user experiences during a cellular telecommunication network outage utilizing a backup data center, the method comprising:
providing, by a mobile network operator, a distributed unit (DU) of a fifth-generation New Radio (5G NR) cellular telecommunication network radio access network (RAN) that is served by a particular 5G NR cellular site base station, wherein the DU:
is associated with a primary 5G NR Next Generation Node B (gNb) identified by a primary identifier (ID); and
is in operable communication with a corresponding primary central unit control plane (CU-CP) of a 5G NR primary centralized unit (CU) that is hosted on a cloud-native virtualized compute instance in a primary physical data center and is also associated with the primary gNb identified by the primary ID;
pre-configuring on the DU a secondary ID of a secondary gNb associated with a secondary CU-CP of a secondary 5G NR CU that is hosted on a backup cloud-native virtualized compute instance in a backup physical data center separate from the primary physical data center;
the DU detecting there exists a failure in communication between the DU and the corresponding primary CU-CP; and
in response to the DU detecting there exists the failure in communication between the DU and the corresponding primary CU-CP, causing the DU to switch from using the corresponding primary CU-CP to using the secondary CU-CP of a secondary CU hosted on the backup cloud-native virtualized compute instance based on utilizing the secondary ID pre-configured on the DU.
