1. A waveguide system, comprising:
- a first physical transmission medium that facilitates propagation of first electromagnetic waves, wherein the first electromagnetic waves convey data;
a second physical transmission medium;
a memory that stores instructions; and
a processor coupled to the memory, wherein responsive to executing the instructions, the processor performs operations, the operations comprising;
detecting a fault that adversely affects the propagation of at least a portion of the first electromagnetic waves along the first physical transmission medium conveying at least a portion of the data; and
responsive to the detecting the fault, generating second electromagnetic waves that propagate along the second physical transmission medium, wherein the second electromagnetic waves convey the at least a portion of the data.

Abstract
A system for detecting a fault in a first wire of a power grid that affects a transmission or reception of electromagnetic waves that transport data and that propagate along a surface of the first wire, selecting a backup communication medium from one or more backup communication mediums according to one or more selection criteria, and redirecting the data to the backup communication medium to circumvent the fault. Other embodiments are disclosed.
