Is it possible to have a third backup name server in case the first two fail?
Recently I had a site go down for about an hour when a CloudFlare datacenter went down. We have the option of setting a tertiary name server. Would this act as a failsafe, or do names servers work on a first come first server basis?
If a tertiary name server isn't the way to go, what's the best way to ensure the site stays up in case Cloudflare fails again?
