While the hyperscalers have been running AI workloads against vast datasets in production for a decade and a half, many large enterprises have lots of data they think is relevant but they are not at all experiences with AI and the system requirements it has. …

Earlier this month, Cloudflare’s systems automatically detected and mitigated a 15.3 million request-per-second (rps) DDoS attack — one of the largest HTTPS DDoS attacks on record.
While this isn’t the largest application-layer attack we’ve seen, it is the largest we’ve seen over HTTPS. HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection. Therefore it costs the attacker more to launch the attack, and for the victim to mitigate it. We’ve seen very large attacks in the past over (unencrypted) HTTP, but this attack stands out because of the resources it required at its scale.
The attack, lasting less than 15 seconds, targeted a Cloudflare customer on the Professional (Pro) plan operating a crypto launchpad. Crypto launchpads are used to surface Decentralized Finance projects to potential investors. The attack was launched by a botnet that we’ve been observing — we’ve already seen large attacks as high as 10M rps matching the same attack fingerprint.
Cloudflare customers are protected against this botnet and do not need to take any action.
What’s interesting is that the attack mostly came from data centers. We’re Continue reading

Enrique Vallejo asked an interesting question a while ago:
When was X.25 official declared dead? Note that the wikipedia claims that it is still in use in parts of the world.
Wikipedia is probably right, and had several encounters with X.25 that would corroborate that claim. If you happen to have more up-to-date information, please leave a comment.

We blogged previously about some trends concerning the first round of the 2022 French presidential election, held on April 10. Here we take a look at the run-off election this Sunday, April 24, that ended up re-electing Emmanuel Macron as President of France.
First, the two main trends: French-language news sites outside France were clearly impacted by the local rule that states that exit polls can only be published after 20:00.
And Internet traffic was similar on both the election days (April 10 and 24) and that includes the increase in use of mobile devices and interest in news websites — there we also saw a clear interest in the Macron-Le Pen debate on April 20.
We have discussed before that election days usually don’t have a major impact on overall Internet traffic. Let’s compare April 10 with 24, the two Sundays when the elections were held. The trends throughout the day are incredibly similar (with a slight increase in traffic on April 24), even with a two-week gap between them.
Another election-day trend is the use of mobile devices to access the Internet, mainly at night. The largest spikes in number of requests made using mobile devices in Continue reading
Nous avons publié un article de blog consacré à certaines tendances concernant le premier tour de l'élection présidentielle française de 2022, qui s'est déroulé le 10 avril. Nous nous intéressons ici au second tour de l'élection, qui a eu lieu le dimanche 24 avril et a abouti à la réélection d'Emmanuel Macron à la présidence de la France.
Tout d'abord, les deux principales tendances : les sites d'information francophones situés hors de France ont été clairement impactés par la réglementation locale, qui stipule que les estimations ne peuvent être publiées qu'après 20 heures.
Le trafic Internet a été similaire les deux jours de l'élection (les 10 et 24 avril), et cela inclut l'augmentation de l'utilisation des appareils mobiles et l'intérêt pour les sites d'actualités – - là aussi, nous avons constaté un net intérêt pour le débat Macron-Le Pen du 20 avril.
Nous avons déjà évoqué le fait que les jours d'élections n'ont généralement pas un impact majeur sur le trafic Internet global. Comparons les journées des 10 et 24 avril, les deux dimanches où ont eu lieu les élections. Les tendances tout au long de la journée sont incroyablement similaires (avec une légère augmentation du trafic le 24 Continue reading
For many years, I’ve been working with B2B IT vendors who sponsor content with my company to market their offerings. My co-founder and I have learned many lessons–some the hard way–about dealing with these vendors and the content they create with us.
In this article, I’ll focus on handling a specific scenario. You’ve got a niche blog where you write as a deeply technical expert in a IT field such as cloud, networking, storage, development, or security. Your audience is made up of fellow nerds in similar orbits. You’ve been writing for years, and have developed a faithful audience who reads most of your stuff. After all this time, a real-deal vendor appears, wanting to place a sponsored blog post on your hallowed site. Now what?
You might think the sponsored content itself would be the most complicated part, and that once you hit publish, you’re mostly done. Not really. Back end logistics will likely take up more of your time. There are other considerations, too. Consider them carefully before trying to monetize your blogging hobby.
If this is your first sponsored post, you might feel weird about it. The temptation can be to hide Continue reading

We built Cloudflare’s Zero Trust platform to help companies rely on our network to connect their private networks securely, while improving performance and reducing operational burden. With it, you could build a single virtual private network, where all your connected private networks had to be uniquely identifiable.
Starting today, we are thrilled to announce that you can start building many segregated virtual private networks over Cloudflare Zero Trust, beginning with virtualized connectivity for the connectors Cloudflare WARP and Cloudflare Tunnel.
Consider your team, with various services hosted across distinct private networks, and employees accessing those resources. More than ever, those employees may be roaming, remote, or actually in a company office. Regardless, you need to ensure only they can access your private services. Even then, you want to have granular control over what each user can access within your network.
This is where Cloudflare can help you. We make our global, performant network available to you, acting as a virtual bridge between your employees and private services. With your employees’ devices running Cloudflare WARP, their traffic egresses through Cloudflare’s network. On the other side, your private services are behind Cloudflare Tunnel, accessible Continue reading
