Currently, to use a custom domain with DigitalOcean Spaces CDN (e.g., cdn.example.com pointing to my-space.fra1.cdn.digitaloceanspaces.com), I need to transfer my entire domain's DNS management to DigitalOcean nameservers. This is problematic because:

Many users prefer managing DNS with Cloudflare for better performance, DDoS protection, and advanced features

Domain consolidation - users want to keep all domains in one DNS provider

Current workarounds are complex - requiring Workers, redirects, or proxies that break the user experience

Proposed Solution:

Allow custom domain verification through:

DNS TXT record verification (like most CDN providers)

CNAME verification method

File-based verification on the domain

Benefits:

Users can keep their preferred DNS provider

Simpler setup process

Better user experience with branded CDN URLs

Competitive with other CDN providers (Cloudflare, AWS CloudFront, etc.)

This would make DigitalOcean Spaces more competitive and user-friendly for developers who want branded CDN URLs without the complexity of full DNS migration.
