# Optimism

Failover protection

Optimism [failover support](/services/concepts/failover-protection/) is available for customers on the Growth or Custom plans. Optimism failover support is available on Mainnet only. Calls to the network are routed to [partner infrastructure providers](#partners-and-privacy-policies).

Optimism is an EVM-compatible, layer 2, rollup scaling solution that operates on top of Ethereum. All transactions that occur on Optimism are posted and validated on Ethereum mainnet using Optimistic Rollups.
