Vercel's Frontend Cloud provides high availability through global anycast routing, multi-AZ and multi-region redundancy with Function Failover, and Edge Config for backend failover without redeployment.

## Evidence

Verbatim from https://vercel.com/blog/effortless-high-availability-for-dynamic-frontends:

> By default, Vercel Functions are deployed across multiple availability zones (AZs) within any given region, enhancing their availability. However, cross-AZ full-region outages can and do very occasionally happen. By activating Function Failover in the Vercel dashboard, customers can provision functions to be automatically deployed in a backup region.
