@rapha3l @marcel @abuse_ch Quad9 does not have the authority to take down domains, however, if they are included in the block lists of our 30+ threat intelligence providers, users will be protected from reaching those sites.

The "Globe of Wonder" (GoW 😻) is certainly living up to its name - making an appearance with our CTO at last week!

@qwertz Then it up to our community to educate them! We're trying!

Glad to see someone is taking notice!
Could the plaintiffs please redirect their effort to the people actually committing the crime? 🤷‍♀️

Today we are very proud to announce the new Internet Pollution Index, a new tracker that visualizes global cyber threat activity in real time, helping network operators, policymakers identify and mitigate malicious Internet behavior.

"After seeing what #MANRS has done for improving #RoutingSecurity, I am optimistic that we can find some common agreed norms for how you find and stop this nonsense in your network before it attacks somebody else, before it trashes the reputation of your IP addresses, and before we have a mess in the Internet."

That was Leslie Daigle's final message to the RIPE NCC community at #RIPE90, after presenting the #InternetPollutionIndex and GCA's work around the #AIDE project.

Proof of Quad9 life (sort of) at - at least we think @f0r573r is behind the camera...looking forward to the presentations and discussions this week in Geneva 🇨🇭!

When #FlaxTyphoon reports emerged, we examined whether its activity was detectable within AIDE, GCA’s #cybersecurity intelligence platform that monitors global network traffic, detects potential threats, and delivers actionable insights to improve network security.

Our analysis revealed behavioral signals and infrastructure overlaps consistent with Flax Typhoon’s tactics—including VPN tunneling, web shell traffic, and credential-based reconnaissance—across sensors located in Taiwan, the United States, Europe, and East Asia.

Key action items for every network operator to take to reduce risk and strengthen network integrity:

👁️ Monitor for unauthorized access attempts and abnormal service behavior.

💪 Strengthen routing security by implementing Mutually Agreed Norms for Routing Security (MANRS) best practices and validating route origins with #RPKI.

🤝 Join collaborative intelligence efforts like AIDE, where shared visibility enables shared defense—and actionable data drives real-world mitigation.

🥳 We've mentioned this before, but now it's official! Retiring the -based service frees up resources in many under-resourced locations to serve our users better. So a reason to celebrate as we continuously strive to improve our service!

Capped off more than a year and a half of hard work this week! EoLed our last core server - deployed during our first year of operations since the org's 2017 launch!

This has allowed us to level up our global infrastructure with faster, smarter tech to boost performance and cut latency for users worldwide - all thanks to our grant from . Go team 💪
