| 5 |  3 BILLION DNS queries.
Almost +1 billion in one week.
OpenBLD started in 2019 as a homegrown project handling around 35K DNS queries a day.
Today:
→ ~15M queries/hour
→ 4K+ queries/second
→ servers distributed around the world
→ billions of DNS queries processed
And it still runs mostly on regular VPS infrastructure - with plenty of performance headroom left.
Getting here required years of optimizing the entire stack: networking, DNS processing, caching, filtering, load balancing, observability, and the Go code itself.
Now the growth is public too:
Real-time OpenBLD network statistics are live on OpenBLD.net.
From 35K/day to 3 billion.
Still building. 🚀
Fast. Private. Open. | 2 749 |
| 6 |  🇰🇿 OpenBLD on Onehost.kz VPS NVMe SSD in Kazakhstan
Under the hood: IPv6, AMD EPYC™, DDR4, NVMe SSD storage, and a high-speed network. A strong candidate for passing OpenBLD’s stress test.
Last year, Onehost.kz supported the OpenBLD project by providing a VPS server in Almaty. Since then, the infrastructure has demonstrated stable 99.99% uptime, with no noticeable overselling or system freezes.
The server in Almaty is now part of the OpenBLD infrastructure, handling a portion of DNS traffic from Almaty, Kazakhstan, and the wider CIS region.
Today, Onehost.kz offers reliable service, reasonable pricing, and solid infrastructure quality.
OpenBLD provides secure DNS protection against malware and other unwanted resources.
Enjoy the stability 🚀 | 181 |

| 8 |  ⚔️ OpenBLD.net: Algorithm (zBLD) vs. Algorithm (DGA)
Malware and botnets use DGA (Domain Generation Algorithm) - algorithms that generate hundreds of "trash" domains per second to communicate with C2 servers.
An attack example from real OpenBLD logs:
• 96bccebb2f7e...wu7y6z[.]com
• 60r...60pg0131[.]cc
• and billions of similar ones...
What's the harm?
Aside from the obvious malicious intent, this chaotic spam clogs the cache, hammers I/O, chews up CPU time, and generates gigabytes of junk logs. As a result—speed degradation and high resource utilization.
How to fight it?
Signatures and blacklists are useless - a total waste of resources, as these domains live for only a matter of minutes.
The Solution is proactive realtime analysis: a detection algorithm against a generation algorithm.
In OpenBLD, the smart DGA detection has been continuously improving and running since 2025 (before that, it spent a whole year being refined, tested, and running in read-only mode).
The Result:
Junk is blocked on the fly. The service preserves resources, while end users get maximum response speed.
Engineering in details ☝️ Speed and protection at the intersection of algorithms:

| 9 |  🚀 OpenBLD.net - Independent DNS Resolution
We’ve become used to relying on DNS from Google, Cloudflare, and other large public DNS providers.
They are fast, convenient, and easy to use. But in the age of AI, large-scale data aggregation, and user profiling, convenience should not come at the cost of privacy.
OpenBLD.net takes a different path.
We are building an independent DNS ecosystem designed to reduce dependency on centralized DNS providers and give users more control over how their DNS traffic is resolved, filtered, and protected.
Today, around 90% of OpenBLD.net DNS resolution runs on our own infrastructure, using our own filtering and DNS request processing mechanisms.
⚡ At the same time, OpenBLD.net provides:
• speed on par with top DNS providers
• global geographic presence
• DNSSEC validation
support for DNS / DoT / DoH
• our own filtering and protection logic
Independence is not a feature - it is the foundation of privacy.
Stay connected ⚡ OpenBLD.net | 222 |
| 10 |  🚀 OpenBLD.net в Сан-Франциско
Благодаря 3HCLOUD.kz в OpenBLD появился новый сервер, в Сан-Франциско.
3HCLOUD за годы показал:
• Стабильная работа сервисов
• Очень адекватные цены
• Несколько локаций по всему миру, включая Казахстан 🇰🇿
• Встроенный Firewall и дополнительные инструменты защиты
• Быстрая и качественная сеть
За годы развития OpenBLD.net через проект прошло немало облачных провайдеров - Не все выдерживают требования, которые предъявляет DNS-инфраструктура.
Можно сказать, что OpenBLD.net стал своеобразным стресс-тестом для облачных платформ.
Именно поэтому особенно приятно отметить, что 3HCLOUD.kz этот тест проходит не один год.
Вместе делаем Интернет быстрее, безопаснее и надёжнее.
Спасибо команде 3HCLOUD.kz за поддержку проекта 🤝 | 240 |
| 11 |  OpenBLD.net: 🤝 ClouDNS.net — quality proven over time
ClouDNS has been part of the OpenBLD.net infrastructure for many years. It’s one of those rare cases where a service consistently proves its quality over time:
• Global network (Anycast + GeoDNS)
• Failover and fallback mechanisms
• Monitoring and health checks
• Stability and SLA
• Cost-effective
OpenBLD.net builds a secure DNS infrastructure. ClouDNS → stable global distribution and availability (GeoDNS, Anycast network with 60+ PoPs worldwide).
• More details: https://www.cloudns.net/
Thank you, ClouDNS, for your trust and long-term partnership 🤝 | 259 |
| 12 |  ⚡ DNS is not just about domains. It is about Trust.
Recent supply chain incidents are a strong reminder that modern attacks often start through tools and workflows developers already trust:
• npm packages and dependency updates
• compromised maintainer accounts
• VSCode extensions
• GitHub Actions workflows
• fake installers and update mechanisms
Several recent cases highlight this trend:
• Axios compromised on npm — malicious versions dropped a Remote Access Trojan >
• Compromised VSCode Nx Console >
• OpenAI response to the TanStack npm supply chain attack >
• OpenAI response to the Axios developer tool compromise >
• GitHub reported an investigation into unauthorized access to internal repositories >
The key takeaway: supply chain attacks are becoming more relevant to every developer, engineering team, and company.
DNS security should not be treated as an optional layer.
It can provide visibility and control when malicious code attempts to:
• connect to C2 infrastructure
• reach phishing domains
• communicate with fake update servers
• exfiltrate data through suspicious endpoints
If malicious code has already entered the environment, visibility becomes critical...
At this point, the key questions are simple:
• Can you see where it is trying to connect?
• Can you understand whether that connection is expected?
• Can you react before the incident becomes bigger?
OpenBLD.net — Security starts earlier than incident response.
Watch yourself, your emails, your extensions, and your DNS. Peace ✌️ | 3 480 |
| 13 | ⚠️ Notice: The Astana server will be maintenance for several days in the coming days. This should not affect overall service availability. If you will have any connectivity issues, contact me please. | 281 |
| 14 |  😎 OpenBLD.net - Dedup DNS Events
Yo! The privacy march continues! 🚀
Anonymized IPs are cool, but now they’re deduplicated too! OpenBLD is rolling out an event deduplication mechanism. Anonymization + Deduplication — what could be better?
Sure, I might be shooting myself in the leg when it comes to incident analysis, but you never know until you try!
An efficient system should be lean and clean, and for a public service — private!
Moving forward!
https://openbld.net/
P.S. Anonymization is already live in the ADA OpenBLD in Europe, CIS regions, including Kazakhstan! | 320 |
| 15 |  🥷 OpenBLD.net — IP Anonymization Implemented
DNS reveals more than you think:
• Every query
• Every domain
• Every query path pattern
• Location
That’s your behavior, it's your live, it's you every day behavior pattern.
That’s your behavior, it's your live, it's you every day behavior pattern.
OpenBLD now supports IP anonymization in short-term troubleshooting logs and metrics:
• masking
• hashing
• flexible anonymization modes
Your data stays yours! 🥷

| 17 |  OpenBLD.net — Forced DNSSEC Under the Hood 🛡
A lot has been achieved over the years, but this past month we’ve rolled out a major update: forced domain digital signature verification (DNSSEC) at the deepest levels of the OpenBLD ecosystem.
What does this give us?
+1 Protection against domain spoofing.
+1 Resilience to attacks.
+1 Security Karma for the whole OpenBLD project.
Security shouldn’t slow you down. That’s why these changes are implemented to ensure top-tier protection stays perfectly in sync with high-speed performance.
This is one more step towards:
• Independence from public DNS monopolists.
• Enhanced privacy.
• Building our own secure, self-sustained infrastructure.
It’s another big plus: +1 to Independence and Privacy.
Stay safe. Peace! ✌️ | 369 |
| 18 |  ⚡️ benZine: Full Throttle for OpenBLD.net!
While you were sleeping (or maybe not), I rebuilt the “engine” of our update system.
Meet benZine — the fuel that hunts malicious DNS signatures all over the world and pumps them straight into OpenBLD servers.
So, what’s changed?
Over the past year, benZine has evolved from a simple script into a powerful ecosystem. The code has been rewritten and delivery fully optimized — now:
• Millions of domains are processed in just a couple of minutes
• Updates reach servers in seconds
Why does this matter for you, me, and all of us?
Before, after a server restart or a database update, there was a small “window” where fresh internet noise could slip through.
That window is now closed. Security policies are applied almost instantly.
OpenBLD.net is becoming not just cleaner — but faster.
We remove digital junk before it even has a chance to think about our traffic)🔥
Thanks for riding along with OpenBLD.net.
More to come. Peace! ✌️ | 377 |

| 20 |  🔥 OpenBLD.net — Defensive Observation & Guard Module (DOGM)
After six months of tuning the monitoring and DGA-domain blocking system,
along with the rollout of the updated RTL release, it’s time to cut dynamic noise out of the main traffic flow.
What this means in practice:
— Real-time blocking of suspicious domains
— Dropping junk DNS packets at the edge
— Reactive bans for aggressive IP addresses
⚠️ Important: DOGM is being rolled out gradually. In rare cases, false positives may occur.
For such situations, feedback is available here:
