🚀 OpenBLD.net and ClouDNS.net Continue Their Partnership in 2025!

ClouDNS is a reliable, fast , and accessible platform for DNS hosting. With a global network of points of presence, instant DNS updates, and powerful GeoDNS 🌎 capabilities, it enables flexible and adaptive DNS management in today’s fast-paced Internet environment.

OpenBLD joined ClouDNS back in 2023 — and since then, the service has proven itself as a stable and trusted foundation for all of DNS and GeoDNS infrastructure.

I'm truly happy to continue this collaboration. Without ClouDNS, OpenBLD would not have become the service it is today — and I’m very grateful for that.

Peace to all ✌️

🔸OpenBLD.net✌️Speed is invisible. Until you feel it.

We usually notice speed only when it’s gone.

OpenBLD.net just got even faster:

Instant DoH on iOS
Faster page loads in browsers
Less latency = more freedom

👉 Just set it and forget it.
While others wait for a response — you’re already one step ahead.

🔐 OpenBLD.net — Blocking Trojanized PuTTY and WinSCP

A new malvertising campaign is distributing trojanized PuTTY and WinSCP through SEO‑poisoned websites.
These domains are already blocked by OpenBLD.net at the DNS level.

DNS filtering is key to preventive user and infrastructure protection.

🔄 Next week we’re enabling smart rate limiting on all OpenBLD DoH servers

Automatic detection and blocking of anomalies without affecting legitimate traffic.

This won’t affect current users in any way (unless you’re an abuser).
But if something goes wrong, please let me know: @sysadminkz

Thanks to everyone using OpenBLD.net! ✌️

Anti-abuse in OpenBLD.net flags suspicious traffic and sends the source straight to /dev/null.
It’s a tough but precise method — triggered only when real malicious activity is detected.

If you hit a timeout on OpenBLD.net — it doesn’t mean the service is down. It means OpenBLD protected its ecosystem from suspicious traffic into your network!

Just message us — we’ll sort it out. Peace ✌️

// ====== ====== ====== //

Анти-абуз в OpenBLD.net помечает подозрительный трафик и отправляет источник в /dev/null. Это жёсткий, но точный метод — он срабатывает только когда реально фиксируется вредоносная активность.

Если ты словил таймаут на OpenBLD.net — это не значит, что сервис упал. Это значит, что OpenBLD защитил свою экосистему от подозрительного трафика в твою сеть!

Просто напиши — разберёмся. Мир ✌️

🛡 OpenBLD.net — Boosting Security & Performance

The latest release brings major improvements to traffic filtering mechanisms:

RateLimiter has been rewritten to be asynchronous, adaptive, and lock-free — eliminating bottlenecks and stalls under high pressure.

- Geographic scale-up and user base growth accounted for
- Enhanced sanitization of malicious traffic
- Improved handling of parasitic IPs (e.g., abused, noisy, or tunneling endpoints)
Increased performance under high concurrency

📈 Noticeable performance gains across European servers — especially under thousands of DNS queries per second.

🎯 Main goal isn’t just to block, but to filter effectively and on time, saving precious milliseconds.

🔄 The update will be done quickly, within a few days, this should not affect anyone, but if suddenly - Welcome)

🛞OpenBLD: Release Wllr in Production!

The new release, codenamed Wllr, makes the DNS filter even faster and more reliable.

+ New strict hostname validator (RFC 1035/1123): non-standard and suspicious names are blocked immediately.
+ Optimized signature loading: updates are now faster and more stable.
+ Fast troubleshooting logging in hot paths: higher QPS without extra overhead.
+ Performance has caught up with Gram — which was the fastest release of the year thanks to fewer security checks.

The combination of speed and security is what we put into every release.

Keep evolving with OpenBLD.net 🚀

🛡 OpenBLD.net — Invisible DNS Protection for Everyday Security

OpenBLD — DNS filtering continues to be strengthened, evolving into a reliable security layer rather than just a resolver.

Over the past weeks several core mechanisms have been enhanced:

Validator ASCII — strict domain validation based on RFC standards
Abuse Module — fast blocking of suspicious sources
Rated Module — added sharding to protect against overload and DoS
Unicode Detector — preparing basic protection against IDN homograph attacks and phishing

DNS is not only about speed — it’s a Security Assistant, quietly protecting users every day.

🚀 OpenBLD.net — the evolution of DNS security continues.

ℹ️ The update will be rolled out across all ADA instances within the upcoming week.

🛰 OpenBLD.net теперь и в Астане!

Первый DNS-сервер в столице Казахстана — запущен при поддержке NOVA Cloud.

OpenBLD становится ещё ближе к пользователям — и в прямом, и в цифровом смысле.
Быстрый отклик, надёжная фильтрация, защита от фишинга и трекеров прямо здесь - рядом.

🔧 Что нового с запуском узла в Астане:

• Ещё более быстрый отклик в столице и северных регионах
• Доступ по безопасным протоколам: DNS-over-HTTPS (DoH), DNS-over-TLS (DoT)
• Снижение нагрузки и ускорение отклика благодаря интеллектуальному распределению трафика
• DNS-фильтрация теперь ещё стабильнее при высоких нагрузках
Гео-распределение трафика между городами-миллионниками: Астана, Алматы, Шымкент

Спасибо NOVA Cloud Kazakhstan за доверие и техническую поддержку!

Это важный шаг для цифровой экосистемы Казахстана и развития безопасного интернета — когда инфраструктура размещается здесь, у нас, в Казахстане 🇰🇿

💡 Интернет без лишнего шума, слежки и кибер-угроз — это не магия, это OpenBLD.net

📌 Подключиться:
🇰🇿 KZ — https://openbld.net/kz/
RU — https://openbld.net/ru/

Хочешь и ты запустить узел в своём городе или регионе?

Напиши — расскажу как! ✌️

🇫🇷New OpenBLD.net Server in Paris

Paris is a global center of culture, art, and technology.
Today, OpenBLD.net becomes even closer to the people living in this remarkable city and its surrounding regions.

I’m excited to introduce a new OpenBLD.net point of presence in Paris.

The server is now integrated through GeoDNS and will serve users in France and nearby regions — faster, more stable, and more secure.

OpenBLD.net — your clean and safe internet.

Be yourself. Stay in focus.! ✌️

OpenBLD.net is entering a new era of performance. 🚀

Over the past months, I’ve been working on a major upgrade of the zBLD core.

The focus is clear — acceleration, resilience, and predictable performance under load.

Key improvements:

- Multi-level Rate Limiter (RTL) to absorb traffic spikes
- Thread separation & sharding — reducing pressure on the main processing path
- ~30% of operations moved to async execution
- Stricter RFC-based DoH traffic validation — less “garbage,” lower latency
- Error sampling for unstable clients — reduced disk I/O load
- Reworked domain-filtering engine
- Improved detection of suspicious / DGA domains
- Optimized Linux networking stack and I/O behavior

Result: overall throughput increased by roughly 2×, and priority domains now resolve even faster thanks to smarter deferred analysis.

The update rollout is planned for mid–late December.

Only forward! 💪 Be yourself, be focused!
