🆕 on Cloudflare Radar: a lightweight network quality test measuring upload/download speeds and idle/loaded latency. 📈 It also shows how your results compare to the averages for your your country/region and ISP. ➡️Try it out at radar.cloudflare.com/speedtest

Trade-secret of the day: add this MCP server and ask anything about Internet traffic trend or routing. It's unbelievably powerful.

Do you use the Radar MCP server? It now exposes normalization parameters, so you can compare HTTP traffic data using MIN0_MAX or PERCENTAGE normalization. Learn more about the Radar MCP server at github.com/cloudflare/mcp…

Whatever may come next from Iran, @Cloudflare is well aware of their techniques, not worried, and fully prepared to defend our customers.

Yesterday a quasi-judicial body in Italy fined @Cloudflare $17 million for failing to go along with their scheme to censor the Internet. The scheme, which even the EU has called concerning, required us within a mere 30 minutes of notification to fully censor from the Internet any sites a shadowy cabal of European media elites deemed against their interests. No judicial oversight. No due process. No appeal. No transparency. It required us to not just remove customers, but also censor our 1.1.1.1 DNS resolver meaning it risked blacking out any site on the Internet. And it required us not just to censor the content in Italy but globally. In other words, Italy insists a shadowy, European media cabal should be able to dictate what is and is not allowed online. That, of course, is DISGUSTING and even before yesterday’s fine we had multiple legal challenges pending against the underlying scheme. We, of course, will now fight the unjust fine. Not just because it’s wrong for us but because it is wrong for democratic values. In addition, we are considering the following actions: 1) discontinuing the millions of dollars in pro bono cyber security services we are providing the upcoming Milano-Cortina Olympics; 2) discontinuing Cloudflare’s Free cyber security services for any Italy-based users; 3) removing all servers from Italian cities; and 4) terminating all plans to build an Italian Cloudflare office or make any investments in the country. Play stupid games, win stupid prizes. While there are things I would handle differently than the current U.S. administration, I appreciate @JDVance taking a leadership role in recognizing this type of regulation is a fundamental unfair trade issue that also threatens democratic values. And in this case @ElonMusk is right: #FreeSpeech is critical and under attack from an out-of-touch cabal of very disturbed European policy makers. I will be in DC first thing next week to discuss this with U.S. administration officials and I’ll be meeting with the IOC in Lausanne shortly after to outline the risk to the Olympic Games if @Cloudflare withdraws our cyber security protection. In the meantime, we remain happy to discuss this with Italian government officials who, so far, have been unwilling to engage beyond issuing fines. We believe Italy, like all countries, has a right to regulate the content on networks inside its borders. But they must do so following the Rule of Law and principles of Due Process. And Italy certainly has no right to regulate what is and is not allowed on the Internet in the United States, the United Kingdom, Canada, China, Brazil, India or anywhere outside its borders. THIS IS AN IMPORTANT FIGHT AND WE WILL WIN!!!

A very powerful retirement press conference. It was about @Uz_Khawaja’s cricket career but was an incredible window into what it is to be a brown person in a largely white environment. You start with trying to fit in but then realise it’s more about being accepted for who you are

What should @Cloudflare build in 2026?

thought to try my hand at tackling some of cloudflare's enterprise products take a look at zero trust and let me know what you think 👀 ztna.momito.co.uk

Reliability is our top priority. We have declared "Code Orange: Fail Small" to focus our engineering efforts on a single goal: ensuring the causes of past outages are fundamentally eliminated. Here is how we are building a more resilient network for the future. cfl.re/49j9joy

In the US, with Thanksgiving yesterday, Internet traffic (human-related) dropped significantly starting in the morning, and it hit its biggest drop around 21:00 UTC (16:00 ET; 13:00 PT), with 25% less traffic than the previous week. Last year, traffic dropped as much as 27%.

@KankaniAbhishek @Cloudflare 👋🏾💪🏾

Hey there @Cloudflare 👋

Speed is always important! The newest version of the BIRD route server software (version 3.1) is here, and it performs very well. It can easily manage connections with 2000 or more other networks (often called peers). This is particularly good news for @DECIX biggest Internet Exchange Points (IXPs). @DECIX Frankfurt connects over 1000 members and is growing rapidly (by 20%!), so this improved capacity really matters. Great work, Maria (@cz_nic)! #euroix

@heymingwei Haha... The README is rather hilarious though 😂

What did I just read...
