Configuring Custom Nameservers for Multi-Region VPS Architectures

As your infrastructure expands across multiple VPS providers and geographical regions, setting up your own authoritative nameservers (using BIND9 or PowerDNS) gives you granular control over geo-DNS routing and latency-based traffic balancing.

Is self-hosting nameservers worth the maintenance overhead, or is it safer to rely on managed DNS providers like Cloudflare, Route53, or DigitalOcean DNS?
