Cloudflare’s mission is to help build a better Internet. We’ve invested heavily in building the world’s most powerful cloud network to deliver a faster, safer and more reliable Internet for our users. Today, we’re taking a big step towards enhancing our ability to secure our customers.
Earlier today we announced that Cloudflare has agreed to acquire Area 1 Security. Area 1’s team has built exceptional cloud-native technology to protect businesses from email-based security threats. Cloudflare will integrate Area 1’s technology with our global network to give customers the most complete Zero Trust security platform available.
Back at the turn of the century I was involved in the fight against email spam. At the time, before the mass use of cloud-based email, spam was a real scourge. Clogging users’ inboxes, taking excruciatingly long to download, and running up people’s Internet bills. The fight against spam involved two things, one technical and one architectural.
Technically, we figured out how to use machine-learning to successfully differentiate between spam and genuine. And fairly quickly email migrated to being largely cloud-based. But together these changes didn’t kill spam, but they relegated to a Continue reading
When people think of supercomputers, they think of a couple of different performance vectors (pun intended), but usually the first thing they think of is the performance of a big, parallel machine as it runs one massive job scaling across tens of thousands to hundreds of thousands of cores working in concert. …

This Day Two Cloud Tech Bytes episode, sponsored by Singtel, discusses common customer misconceptions about connecting private networks to the public cloud. For instance, SD-WAN might seem like a simple option, but things get tricky when you're talking about hundreds of sites across different countries. Our guest is Mark Seabrook, Global Solutions Manager at Singtel.

I was a guest on the February 22, 2022 episode of the So You Wanna Be In IT podcast.
I chatted with hosts Pat & Dean about how my career got started. I’ve been around IT since the 90s, so my start was with Novell certification that became Microsoft certification that became Cisco certification. We talk about certs and the job opportunities I took advantage of driven by those certs.
Along the way, we discussed whether or not someone can have a successful IT career without a college degree. Put another way, are IT certifications good enough? I think that yes, you can have a successful IT career without a degree, but that the question, “College degree. Yes or no?” deserves more analysis than a simple yes or no answer offers. Like anything, choosing not to attend university has tradeoffs. We discuss this at some length in the podcast.
The degree vs. certifications part of the discussion transitioned into my takes on IT careers in 2022–especially related to infrastructure. 2022 is an interesting time to be in IT. There are Continue reading
While on-premises datacenters are strategic to large enterprises, and will be for the foreseeable future, hybrid clouds and the edge are also an increasingly important part of the IT platform portfolio. …

Today on the Tech Bytes podcast, we’re talking about how your organization can adopt a hyperscale model in your network to improve TCO, scale out capabilities and services, and get supply chain diversity. Our sponsor is DriveNets, and we’re speaking with Run Almog, Head of Product Strategy.

As organizations grow and expand geographi cally, they start extending their IT infrastructure into the distributed and far edge layers through opening new branch offices.
Restaurants, retail stores, and other customer-centric businesses provide differentiated wireless access for their employees, contractors and customers to interconnect within their designated areas.
Configuring and managing multiple wireless settings via Red Hat Ansible Automation Platform simplifies the deployments at scale.
Network administrators can use GitOps practices to automate wireless infrastructure as a code (IaC).
This case covers a sample use case for a company that uses an SDN (software-defined network) controller with a large network infrastructure, including access points, switches, and firewalls/routers to provide connectivity for thousands of branches across multiple countries. We will show you step by step how to automate wireless network access point settings at scale through a SD-WAN controller, which will be Cisco Meraki for purposes of this demo.
Typically an SDN controller has an API. Having access to an SDN API is an advantage, since we have a single point of contact with the controller, and we can operate the whole network Continue reading
Over the last few years, we have seen an age of edgeless, multi-cloud, multi-device collaboration for hybrid work giving rise to a new network that transcends traditional perimeters. As hybrid work models gain precedence through the new network, organizations must address the cascading attack surface. Reactionary, bolt-on security measures are simply too tactical and expensive.
Ever since the (public) invention of cryptography based on mathematical trap-doors by Whitfield Diffie, Martin Hellman, and Ralph Merkle, the world has had key agreement and signature schemes based on discrete logarithms. Rivest, Shamir, and Adleman invented integer factorization-based signature and encryption schemes a few years later. The core idea, that has perhaps changed the world in ways that are hard to comprehend, is that of public key cryptography. We can give you a piece of information that is completely public (the public key), known to all our adversaries, and yet we can still securely communicate as long as we do not reveal our piece of extra information (the private key). With the private key, we can then efficiently solve mathematical problems that, without the secret information, would be practically unsolvable.
In later decades, there were advancements in our understanding of integer factorization that required us to bump up the key sizes for finite-field based schemes. The cryptographic community largely solved that problem by figuring out how to base the same schemes on elliptic curves. The world has since then grown accustomed to having algorithms where public keys, secret keys, and signatures are just a handful of Continue reading
This is not what I imagined my first blog article would look like, but here we go.
On February 1, 2022, a configuration error on one of our routers caused a route leak of up to 2,000 Internet prefixes to one of our Internet transit providers. This leak lasted for 32 seconds and at a later time 7 seconds. We did not see any traffic spikes or drops in our network and did not see any customer impact because of this error, but this may have caused an impact to external parties, and we are sorry for the mistake.

As part of our efforts to build the best network, we regularly update our Internet transit and peering links throughout our network. On February 1, 2022, we had a “hot-cut” scheduled with one of our Internet transit providers to simultaneously update router configurations on Cloudflare and ISP routers to migrate one of our existing Internet transit links in Newark to a link with more capacity. Doing a “hot-cut” means that both parties will change cabling and configuration at the same time, usually while being on a conference call, to reduce downtime and impact on the network.
