Micro-level network node failover system

Non-transitory, computer-readable storage media comprising computer-executable instructions, wherein the computer-executable instructions, when executed by a computer system, cause the computer system to:

• obtain one or more key performance indicator (KPI) values associated with one or more nodes in a core network that offer a first service, wherein the one or more KPI values are associated with the first service;
• compare a first KPI value in the one or more KPI values with a first threshold value;
• determine that the first KPI value exceeds the first threshold value;
• determine that the first KPI value corresponds with a first node in the one or more nodes;
• and
• instruct the first node to re-route requests corresponding to the first service to a second node in the one or more nodes that is redundant to the first node.

A core network comprising:

• one or more nodes that each offer a first service;
• and
• a failover and isolation server (FIS) comprising a processor in communication with the one or more nodes and configured with specific computer-executable instructions to:
• obtain one or more key performance indicator (KPI) values associated with the one or more nodes, wherein the one or more KPI values are associated with the first service;
• compare a first KPI value in the one or more KPI values with a first threshold value;
• determine that the first KPI value exceeds the first threshold value;
• determine that the first KPI value corresponds with a first node in the one or more nodes;
• and
• initiate a failover operation with respect to the first node such that the first node redirects requests corresponding to the first service to a second node in the one or more nodes that is redundant to the first node.
