Failover is an automatic switch to a backup system if the primary server or network path fails. In forex hosting, failover mechanisms (such as a standby duplicate server or redundant network links) help maintain continuous trading even if hardware faults or data-center issues occur. For example, a hosting provider might mirror your trading platform on two servers: if the main server crashes, connections seamlessly move to the backup so your robots keep running. Failover is a key part of high-availability setups for trading infrastructure.
