Improving the Resiliency of Our Infrastructure DNS Zone

What this post added

Introduced a multi-primary authoritative nameserver setup for the infrastructure DNS zone, using both Cloudflare's edge and a third-party DNS provider. Implemented OctoDNS for managing zone data across providers and developed custom source modules (ProvAPI, NetBox) for automated record provisioning. Modified DNSDist configuration to implement weighted routing and active checks for internal DNS resolution, preferring Cloudflare's infrastructure when available and failing over to the third-party provider during outages.
