When a #server goes down, it means the server has become unavailable or unresponsive due to hardware failure, software issues, network problems, or overload. This downtime can interrupt services, prevent users from accessing data, and cause business disruptions. To minimize such risks, organizations often implement replication — a process of copying and maintaining data across multiple servers or databases.

#Replication ensures that even if one server fails, another can immediately take over, maintaining data availability and reliability. It helps in load balancing, disaster recovery, and performance improvement. For example, in a database system, replication can be synchronous (data is updated on all replicas instantly) or asynchronous (data is updated later). Synchronous replication offers higher consistency but may affect performance, while asynchronous replication provides better speed but can have slight data delays.

In summary, server replication is a critical strategy for ensuring system resilience and minimizing downtime, allowing services to remain operational even during unexpected server failures.
