How Cloudflare provides tools to help keep IPFS users safe
Cloudflare's journey with IPFS started in 2018 when we announced a public gateway for the distributed web. Since then, the number of infrastructure providers for the InterPlanetary FileSystem (IPFS) has grown and matured substantially. This is a huge benefit for users and application developers as they have the ability to choose their infrastructure providers.
Today, we’re excited to announce new secure filtering capabilities in IPFS. The Cloudflare IPFS module is a tool to protect users from threats like phishing and ransomware. We believe that other participants in the network should have the same ability. We are releasing that software as open source, for the benefit of the entire community.
Its code is available on github.com/cloudflare/go-ipfs. To understand how we built it and how to use it, read on.
A brief introduction on IPFS content retrieval
Before we get to understand how IPFS filtering works, we need to dive a little deeper into the operation of an IPFS node.
The InterPlanetary FileSystem (IPFS) is a peer-to-peer network for storing content on a distributed file system. It is composed of a set of computers called nodes that store and relay content using a common addressing system.
Nodes communicate with each other Continue reading
IAB Workshop on Measuring Network Quality for End Users
The telephone network had a single task: make human voice conversations work well. IP networks have a more challenging objective: make all kinds of digital transactions work well. From first player shooter games, though video streaming and web transactions through to human conversations. Make 'em all work well. This topic has become one of those long-standing sagas in IETF folklore, and another chapter of the evolving story was written at a recent IAB Workshop on Measuring Network Quality for End Users. Here's my impressions of this workshop.Day Two Cloud 117: How Akamai Helped Transform IBM Cloud Console’s Architecture (Sponsored)
Today on the Day Two Cloud podcast we have a sponsored show with Akamai and a customer, IBM Cloud. When IBM rebuilt its Cloud Console from a monolithic application to microservices, the company turned to Akamai to help improve application performance while also supporting routing, failover, and availability across six global data centers. We get details from Pavel Despot, Sr. Product Marketing Manager at Akamai; and Tony Erwin, Senior Technical Staff Member/Architect at IBM.

Smart packet capture (PCAP) gives analysts the ability to choose the packet evidence they collect and make it retrievable via SIEM.How Your Network Can Solve Your Digital Dilemma
In the drive to successful transformation, the underpinning computer network on which that change relies is taken for granted to just magically deliver what is needed. But that’s a strategic mistake, suggests Lars Rossen of Micro Focus, who wants the network treated as a product.Hedge 102: BGP Security with Geoff Huston
Our community has been talking about BGP security for over 20 years. While MANRS and the RPKI have made some headway in securing BGP, the process of deciding on a method to provide at least the information providers need to make more rational decisions about the validity of individual routes is still ongoing. Geoff Huston joins Alvaro, Russ, and Tom to discuss how we got here and whether we will learn from our mistakes.
Cloudflare for Offices
Cloudflare's network is one of the biggest, most connected, and fastest in the world. It extends to more than 250 cities. In those cities, we're often present in multiple data centers in order to connect to as many networks and bring our services as close to as many users as possible. We're always asking ourselves: how can we get closer to even more of the world's Internet users?
Today, we're taking a big step toward that goal.
Introducing Cloudflare for Offices. We are creating strategic partnerships that will enable us to extend Cloudflare's network into over 1,000 of the world's busiest office buildings and multi-dwelling units. These buildings span the globe, and are where millions of people work every day; now, they’re going to be microseconds away from our global network. Our first deployments will include 30 Hudson Yards, 4 Times Square, and 520 Madison in New York; Willis Tower in Chicago; John Hancock Tower in Boston; and the Embarcadero Center and Salesforce Tower in San Francisco.
And we're not done. We've built custom secure hardware and partnered with fiber providers to scale this model globally. It will bring a valuable new resource to the literal doorstep of Continue reading
Dark Mode for the Cloudflare Dashboard
Today, dark mode is available for the Cloudflare Dashboard in beta! From your user profile, you can configure the Cloudflare Dashboard in light mode, dark mode, or match it to your system settings.
For those unfamiliar, dark mode, or light on dark color schemes, uses light text on dark backgrounds instead of the typical dark text on light (usually white) backgrounds. In low-light environments, this can help reduce eyestrain and actually reduce power consumption on OLED screens. For many though, dark mode is simply a preference supported widely by applications and devices.
How to enable dark mode
- Log into Cloudflare.
- Go to your user profile.
- Under Appearance, select an option: Light, Dark, or Use system setting. For the time being, your choice is saved into local storage.
There are many primers and how-tos on implementing dark mode, and you can find articles talking about the general complications of implementing a dark mode including this straightforward explanation. Instead, we will talk about what enabled us to be able to implement dark mode in Continue reading
Watch Out: ISR Performance License
Bill Dagy sent me an annoying ISR gotcha. In his own words:
Since you have a large audience I thought I would throw this out here. Maybe it will help someone avoid spending 80 man hours troubleshooting network slowdowns.
Here’s the root cause of that behavior:
Cisco is now shipping routers that have some specified maximum throughput, but you have to buy a “boost license” to run them unthrottled. Maybe everyone already knew this but it sure took us by surprise.
Don’t believe it? Here’s a snapshot from Cisco 4000 Family Integrated Services Router Data Sheet:
