Rage Against the Magic Sand

Rage Against the Magic Sand specializes in DNS infrastructure resilience and high-performance systems programming. With 25+ years of hands-on experience designing DNS architectures and building production-grade Go tools and libraries, I deliver:

• DNS reliability engineering: Architecture reviews, failover strategies, and performance tuning.
• Custom tooling: High-concurrency DNS servers and real-time monitoring.
• Expertise: Having worked with clusters of millions of machines, I know how to handle “scale” and simplify things.

Contact dns@ratms.nl to see how I can help you. I know things.

The following popular Go packages were created by me:

1. Go DNS, the premier DNS package for Go. The successor of Go DNS v1.
2. CoreDNS, a hugely popular DNS server that is the default DNS server in Kubernetes clusters.
3. PKCS11, a Go (C) library to interface with PKCS11 and HSMs.

You need a Go master to fix, or optimize (slow) code? Contact dns@ratms.nl!

About

Rage Against the Magic Sand, founded in 2026, by Miek Gieben to fund open source DNS development of atomdns and Go DNSv2.

Personally I want to make a local, maybe federated, cloud a possibility. Giving control, and privacy back to people.
