When a failover event occurs, Cloudflare updates its DNS records to point to the healthy servers. This means that DNS resolution will resolve to the IP addresses of the available servers. The TTL (Time To Live) of your DNS records influences how quickly the change propagates across the internet. Lower TTLs result in faster failover.
