How do distributed networks ensure uptime during catastrophic failures?

Distributed network architectures maintain uptime and reliability during catastrophic events by spreading resources and functions across multiple nodes or locations. This redundancy ensures that if one node or location goes down due to a catastrophic event, other nodes can still continue to function, thus minimizing downtime and ensuring continuity of service. Additionally, distributed network architectures often incorporate failover mechanisms, load balancing, and disaster recovery processes to further enhance resilience in the face of catastrophic events.
