> Proactive Nameservers is a patent-pending system that optimizes the nameserver delegation for your mission critical domain names. That's a huge negative and I can't believe they think it's a good marketing point. I don't want a patent encumbered, non-standard solution for critical infrastructure. > We must be your domain registrar for this to work. So they're updating the domain record at the registry level to facilitate failover? That's the only scenario I can think of where they _need_ to be your registrar. Assuming that's the case... I've always seen 24-48 hours quoted as the worst case wait when updating nameservers at the registry. I've never seen an explanation of how it works, what's allowed to be cached, how long it actually takes to update, etc.. How do they do it in a way that's suitable for failover? Do they have a special SLA with registries? How would the registries handle a deluge of nameserver updates? Imagine a Cloudflare scale failure and corresponding registry updates. Would the registry servers be able to handle it? I'd love to see a technical explanation of how their proactive nameservers system works.
