Making Cloudflare Pages the fastest way to serve your sites

In an era where visitors expect instant gratification and content on-demand, every millisecond counts. If you’re a web application developer, it’s an excellent time to be in this line of business, but with great power comes great responsibility. You’re tasked with creating an experience that is not only intuitive and delightful but also quick, reactive and responsive – sometimes with the two sides being at odds with each other. To add to this, if your business completely runs on the internet (say ecommerce), then your site’s Core Web Vitals could make or break your bottom line.

You don’t just need fast – you need magic fast. For the past two years, Cloudflare Pages has been serving up performant applications for users across the globe, but this week, we’re showing off our brand new, lightning fast architecture, decreasing the TTFB by up to 10X when serving assets.

And while a magician never reveals their secrets, this trick is too good to keep to ourselves. For all our application builders, we’re thrilled to share the juicy technical details on how we adopted Workers for Platforms — our extension of Workers to build SaaS businesses on top of — to make Pages one Continue reading

Speeding up APIs with Ricochet for API Gateway

Speeding up APIs with Ricochet for API Gateway
Speeding up APIs with Ricochet for API Gateway

APIs form the backbone of communication between apps and services on the Internet. They are a quick way for an application to ask for data or ask that a task be performed by a service. For example, anyone can write a weather app without being a meteorologist: simply ask a weather API for the forecast and display it in your app.

Speed is inherent to the API use case. Rather than transferring bulky files like images and HTML, APIs only share the essential data needed to render a webpage or an app. However, despite their efficiency, Internet latency can still impede API data transfers. If the server processing a user’s API request is located far from that user, the network round trip time can degrade that user’s experience.

Cloudflare's global network is specifically designed to optimize and accelerate internet traffic, including APIs. Our users enjoy features like 11ms DNS responses, load balancing, and Argo Smart Routing, which significantly improve API traffic speed. For web content, Cloudflare customers have always been able to cache their web traffic, serving requests from the closest data center and thereby reducing network round trip time and server processing time to a Continue reading

Introducing the Cloudflare Radar Internet Quality Page

Introducing the Cloudflare Radar Internet Quality Page
Introducing the Cloudflare Radar Internet Quality Page

Internet connections are most often marketed and sold on the basis of "speed", with providers touting the number of megabits or gigabits per second that their various service tiers are supposed to provide. This marketing has largely been successful, as most subscribers believe that "more is better”. Furthermore, many national broadband plans in countries around the world include specific target connection speeds. However, even with a high speed connection, gamers may encounter sluggish performance, while video conference participants may experience frozen video or audio dropouts. Speeds alone don't tell the whole story when it comes to Internet connection quality.

Additional factors like latency, jitter, and packet loss can significantly impact end user experience, potentially leading to situations where higher speed connections actually deliver a worse user experience than lower speed connections. Connection performance and quality can also vary based on usage – measured average speed will differ from peak available capacity, and latency varies under loaded and idle conditions.

The new Cloudflare Radar Internet Quality page

A little more than three years ago, as residential Internet connections were strained because of the shift towards working and learning from home due to the COVID-19 pandemic, Cloudflare announced the speed.cloudflare.com Continue reading

A step-by-step guide to transferring domains to Cloudflare

A step-by-step guide to transferring domains to Cloudflare

Transferring your domains to a new registrar isn’t something you do every day, and getting any step of the process wrong could mean downtime and disruption. That’s why this Speed Week we’ve prepared a domain transfer checklist. We want to empower anyone to quickly transfer their domains to Cloudflare Registrar, without worrying about missing any steps along the way or being left with any unanswered questions.

Domain Transfer Checklist

Confirm eligibility

  • Confirm you want to use Cloudflare’s nameservers: We built our registrar specifically for customers who want to use other Cloudflare products. This means domains registered with Cloudflare can only use our nameservers. If your domain requires non-Cloudflare nameservers then we’re not the right registrar for you.
  • Confirm Cloudflare supports your domain’s TLD: You can view the full list of TLDs we currently support here. Note: We plan to support .dev and .app by mid-July 2023.
  • Confirm your domain is not a premium domain or internationalized domain name (IDNs): Cloudflare currently does not support premium domains or internationalized domain names (Unicode).
  • Confirm your domain hasn’t been registered or transferred in the past 60 days: ICANN rules prohibit a domain from being transferred if it has been registered or previously transferred Continue reading

Cisco Guns For InfiniBand With Silicon One G200

It was a fortuitous coincidence that Nvidia was already working on massively parallel GPU compute engines for doing calculations in HPC simulations and models when the machine learning tipping point happened, and similarly, it was fortunate for InfiniBand that it had the advantage of high bandwidth, low latency, and remote direct memory access across GPUs at that same moment. …

How to detect and stop DDoS attacks in a Kubernetes environment

DDoS or Distributed Denial of Service attacks have been around for a while and are notorious and painful to deal with (as with any other attack). As the name suggests, a DDoS attack causes an application or service to become unavailable to users due to resources exceeding it’s capacity and causing the app to either crash or become unresponsive. DDoS is a form of DoS where the attack comes from multiple sources (bots), usually spread across geographical locations. Imagine getting thousands of spam calls on your phone within a very short time and there is one legitimate call that is trying to contact you. How will you make sure you attend the legitimate call?

In a Kubernetes environment, DDoS can hit the application from external sources when a service is exposed to the Internet. For attackers who gain a foothold of the environment within the Kubernetes cluster and are looking to infect multiple workloads with malware to further amplify a DoS attack, you need a strong zero-trust workload access control policies in place to restrict lateral movement.

Why you should invest in a DDoS solution for your container application

Speeding up your (WordPress) website is a few clicks away

Speeding up your (WordPress) website is a few clicks away

Every day, website visitors spend far too much time waiting for websites to load in their browsers. This waiting is partially due to browsers not knowing which resources are critically important so they can prioritize them ahead of less-critical resources. In this blog we will outline how millions of websites across the Internet can improve their performance by specifying which critical content loads first with Cloudflare Workers and what Cloudflare will do to make this easier by default in the future.

Popular Content Management Systems (CMS) like WordPress have made attempts to influence website resource priority, for example through techniques like lazy loading images. When done correctly, the results are magical. Performance is optimized between the CMS and browser without needing to implement any changes or coding new prioritization strategies. However, we’ve seen that these default priorities have opportunities to improve greatly.

In this co-authored blog with Google’s Patrick Meenan we will explain where the opportunities exist to improve website performance, how to check if a specific site can improve performance, and provide a small JavaScript snippet which can be used with Cloudflare Workers to do this optimization for you.

What happens when a browser receives the response?

Speed matters, especially when it comes to exiting a slower service and transitioning to a new one. Back in March, 2023, we announced the Descaler Program, a frictionless path to migrate existing Zscaler customers to Cloudflare One. This program makes it easy for customers to make the switch to a faster, simpler, and more agile foundation for security and network transformation with Cloudflare.

Through repeated engagements with customers of all sizes, we've improved the Descaler tooling to allow Zscaler to Cloudflare configuration migrations to be completed in hours, not days. This accelerated transition has helped organizations meet migration deadlines and eliminate countless hours of manual migration effort without skipping a beat. Today we’re excited to share more stories from customers and the amount of time it took them to ‘descale’.

Benchmarking dashboard performance

Benchmarking dashboard performance
Benchmarking dashboard performance

In preparation of Cloudflare Speed Week 2023, we spent the last few weeks benchmarking the performance of a Cloudflare product that has gone through many transformations throughout the years: the Cloudflare dashboard itself!

Limitations and scope

Optimizing for user-experience is vital to the long-term success of both Cloudflare and our customers. Reliability and availability of the dashboard are also important, since millions of customers depend on our services every day. To avoid any potential service interruptions while we made changes to the application’s architecture, we decided to gradually roll out the improvements, starting with the login page.

As a global company, we strive to deliver the best experience to all of our customers around the world. While we were aware that performance was regional, with regions furthest from our core data centers experiencing up to 10 times longer loading speeds, we wanted to focus on improvements that would benefit all of our users, no matter where they geographically connect to the Dashboard.

Finally, throughout this exercise, it was important to keep in mind that our overall goal was to improve the user experience of the dashboard, with regards to loading performance. We chose to use a Lighthouse Performance score as Continue reading
