 To increase availability and fault tolerance, you can use one or more DNS provider(s) alongside Cloudflare in case one provider becomes unavailable (known as a [peer DNS server](#peer-dns-server)). Your providers will then transfer DNS records between themselves using authoritative ([AXFR](https://datatracker.ietf.org/doc/html/rfc5936)) or incremental ([IXFR](https://datatracker.ietf.org/doc/html/rfc1995)) zone transfers.
