We are pleased to announce a significant infrastructure upgrade. Our servers now run on AMD EPYC 7542 (Zen 2) processors, delivering higher single-thread performance and a substantially larger L3 cache. This directly translates to faster DNS resolution times and improved capacity during traffic spikes.
To take full advantage of the new hardware, we have recompiled every critical component from source with native CPU optimizations. This includes Nginx 1.29.6 with BoringSSL for modern TLS performance, Unbound for recursive resolution, and our packet processing pipeline-all built specifically for the Zen 2 microarchitecture.
Memory has also been expanded, allowing us to maintain larger DNS caches and handle more concurrent connections without compromising response times. Internal benchmarks show a measurable improvement in query latency across all supported protocols.
We have migrated to AMD EPYC Zen 2 processors and recompiled our entire software stack from source with platform-native optimizations for maximum throughput.
Highlights
- AMD EPYC Zen 2 processors with expanded L3 cache
- Nginx 1.29.6 compiled from source with BoringSSL
- Unbound recompiled with native CPU optimizations
- Expanded memory for larger DNS caches and higher concurrency
- Reduced query latency across DoH, DoT, DoQ and standard DNS
