I’m excited to say that I’ve recently joined the Cloudflare team as Head of Japan. Cloudflare has had a presence in Japan for a while now, not only with its network spanning the country, but also with many Japanese customers and partners which I’m now looking forward to growing with.
Today a configuration error in our backbone network caused an outage for Internet properties and Cloudflare services that lasted 27 minutes. We saw traffic drop by about 50% across our network.
Learning how to do server-side rendering at the network edge using Workers Sites, Wrangler, HTMLRewriter, and tools from the broader Workers platform.
We have expanded our global network to 206 cities across more than 100 countries. This is in addition to completing 40+ datacenter expansion projects and adding over 1Tbps of bandwidth capacity to our global backbone so-far in 2020.
Globally, more than 3.5 billion people are still not connected to the internet. With average data usage per person growing 20 to 30 percent annually, legacy bandwidth-limited technologies have been pushed to their capacity limits. To meet this increased demand for high-capacity, low-cost networks, mobile network operators have upgraded access technologies from 2G and 3G […]
Now that Firefox Nightly supports HTTP/3 we thought we'd share some instructions to help you enable and test it yourselves.
Configure custom DNS Records for your Domains and apply presets. Right in the Web UI.
We own and operate physical infrastructure for our backend services. We need an effective way to route arbitrary TCP and UDP traffic between services and also from outside these data centers.
I'm excited to announce the upcoming launch of Cloudflare TV. A 24x7 live television broadcast, streamed globally via the Cloudflare network. You can tune in to the pre-broadcast station and check out the upcoming schedule at: cloudflare.tv
Automatically export DNS query logs from Cloudflare Gateway to your SIEM.
DNS is the very first step in accessing any website, API, or pretty much anything on the Internet, which makes it mission-critical to keeping your site up and running. This week, we are launching two significant changes that allow our customers to better maintain and update their DNS records.
Connectivity is at the heart of our mission to give people the power to build community. We are committed to bringing more people online to a faster internet — and with 3.5 billion people globally unconnected, there is still a lot to do. Africa is currently the least connected continent, with just over a quarter […]
Our connectivity efforts focus on expanding internet access and adoption around the world. This includes our work on technologies like Terragraph, our collaboration with mobile operators on efforts to expand rural access, our work as part of the Telecom Infra Project, and programs like Free Basics. As we’ve continued working on Free Basics, we’ve listened […]

Cloudflare Access replaces legacy corporate VPNs with Cloudflare’s global network. Using your existing identity provider, Access lets your end users to login from anywhere.
Dropbox LAN Sync is a feature that allows you to download files from other computers on your network, saving time and bandwidth compared to downloading them from Dropbox servers. As the number of companies and offices using Dropbox has increased, the use cases for LAN Sync have grown, and the feature was recently rewritten and improved. Here’s a look inside how it works.
Cloudflare employs more than 1,200 people in 13 different offices and maintains a network that operates in 200 cities. To do that, we used to suffer through a traditional corporate VPN that backhauled traffic through a physical VPN appliance.
Today’s Internet requires stronger protection within its core routing system and as we have already said: it's high time to stop BGP route leaks and hijacks by deploying operationally-excellent RPKI!
At Cloudflare, we encrypt data both in transit (on the network) and at rest (on the disk). Both practices address some of the most common vectors used to exfiltrate information and these measures serve to protect sensitive data from attackers but, what about data currently in use?
High-quality internet access opens new opportunities to make yourself heard, connect with the people and communities you care about, and build new businesses. It’s also good for industries and businesses of all kinds, including Facebook. The latest edition of our Inclusive Internet Index shows progress on bringing broadband access to more people, but the rate […]
We designed and built Cloudflare’s network to be able to grow capacity quickly and inexpensively; to allow every server, in every city, to run every service; and to allow us to shift customers and traffic across our network efficiently.
On the Microsoft Edge team, we’re committed to an open web and helping to drive innovation forward, which is why we’ve kicked off a new initiative in

It's HighScalability time: .A network visualization of an information operation on Twitter which originated in Russia (Watch six decade-long disinformation operations unfold in six minutes) Do you like this sort of Stuff? Your support on Patreon is appreciated more than you can know. I also wrote Explain the Cloud Like I'm 10 for everyone who needs to understand the cloud (which is everyo
We’re taking a look at the brand new version of Microsoft Edge and its Chromium-based rendering engine. What does that change mean for web developers, and how does the death of Microsoft’s own rendering engine impact the web? Today, Drew McLellan talks to Microsoft’s Aaron Gustafson and Stephanie Stimac to find out.
Since launch, Cloudflare Access has helped improve how users connect to secured applications. When you protect an application with Access, users never have to connect to a private network and never have to deal with a clunky VPN client.
Cloudflare Access can help teams build a defense-in-depth mitigation to the Citrix NetScaler CVE for HTTP and SSH requests.
Significant work has gone into optimizing TCP, UDP hasn't received as much love, putting QUIC at a disadvantage. Let's explore a few tricks that help mitigate this.

The microservice architectural pattern is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management
