In reality, planning against failure is simply Good Engineering

Real Networks (TM) guard against single/multiple points of failure

- They own an AS to define themselves
- They own their own network prefixes
- They use BGP on multiple edge routers 
- They advertise their network to multiple providers and peers
- They use multiple physical network links, at multiple locations

Multi-homing is what makes the Internet resilient.
