Starting today, Cloudflare Access can now be used in the Cloudflare for Teams dashboard. You can manage security policies for your people and devices in the same place that you build zero-trust rules to protect your applications and resources. Everything is now in one place in a single dashboard.
We are excited to launch a new UI that can be used across the entire Teams platform, but we didn’t build this dashboard just for the sake of a new look-and-feel. While migrating the Access dashboard, we focused on solving one of the largest sources of user confusion in the product.
This post breaks down why the original UI caused some headaches, how we think about objects in Cloudflare for Teams, and how we set out to fix the way we display that to our users.
Cloudflare Access is one-half of Cloudflare for Teams, a security platform that runs on Cloudflare’s network. Teams protects users, devices and data without compromising experience or performance. We built Cloudflare Access to solve our own headaches with private networks as we grew from a team concentrated in a single office to a globally distributed organization.
Cloudflare Access replaces corporate VPNs with Cloudflare’s Continue reading

Yesterday I posted a tweet on company culture that received a lot of positive feedback:
People thought this should be saved in a blog post, so this is it.
Do you want to attract and retain talent and high performers? Of course you do. Do you understand how to do that and are you willing to change your company culture?
Everything starts with culture. You may have heard the quote “Culture eats strategy for breakfast”, meaning that even the best stratety can’t compete with a company that has a great culture. Strategy without culture does not create success.
Most companies, such as the web scalers, often confuse gimmicks with culture. We have great company culture! We have ping pong tables, flipper games and even artists who play music for us! While these things can be entertaining, don’t mistake them for culture. Continue reading
Searching for a signal: CNN has a story about a teacher in rural Virginia who drives 20 minutes to find a good WiFi signal in order to work. The middle school history teacher is one of about 18 million U.S. residents who lack access to high-speed broadband, according to the Federal Communications Commission. The teacher “lives in a valley between two mountains, where the only available home internet option is a satellite connection. Her emails can take 30 seconds to load, only to quit mid-message. She can’t even open files on Google Drive, let alone upload lesson modules or get on a Zoom call with colleagues.”
Demanding access: Meanwhile, in Oakland, California, hundreds of teachers and students are calling for free access to the Internet, demanding that the school district and mayor “take all necessary measures” to ensure that students have access, KTVU reports. “There is no equity in education for our most vulnerable students if all Oakland families do not have access to the internet,” said Keith Brown, president of the Oakland Education Association, said.
Legislating access: In the U.S. Congress, Senate Democrats are introducing a bill that would create a new $4 billion fund for schools Continue reading
Got mentioned in this tweet a while ago:
Watching @ApstraInc youtube stream regarding BGP in the DC with @doyleassoc and @jtantsura.Maybe BGP is getting bigger and bigger traction from big enterprise data centers but I still see an IGP being used frequently. I am eager to have @ioshints opinion on that hot subject.
Maybe I’ve missed some breaking news, but assuming I haven’t my opinion on that subject hasn’t changed.

Cluster API (CAPI) is a relatively new project aimed at deploying Kubernetes clusters using a declarative API (think YAML). The official documentation (a.k.a. the Cluster API book), does a very good job explaining the main concepts and goals of the project. I always find that one of the best ways to explore new technology is to see how it works locally, on my laptop, and Cluster API has a special “Docker” infrastructure provider (CAPD) specifically for that. However, the official documentation for how to setup a docker managed cluster is very poor and fractured. In this post, I’ll try to demonstrate the complete journey to deploy a single CAPI-managed k8s cluster and provide some explanation of what happens behind the scene so that its easier to troubleshoot when things go wrong.
Two things must be pre-installed before we can start building our test clusters:
We’re gonna need run a few scripts from the Cluster API Github repo, so let’s get a copy Continue reading

Over the past several months the Internet Society has been working on a transaction to sell Public Interest Registry (PIR), operator of .ORG and other top-level domains, to Ethos Capital. Under PIR’s registry agreements, the Internet Corporation for Assigned Names and Numbers (ICANN) had to consent to this indirect change of control. ICANN has now announced that it does not consent to the transaction.
I am, of course, disappointed by ICANN’s decision, though I am pleased it was finally reached. ICANN took much longer than it should have done to vote on the transaction. In my view, ICANN stepped outside its remit by acting as a regulator it was never intended to be. What began as a routine change of indirect control – the type ICANN has expeditiously approved on multiple occasions in the past – resulted in months and months of review and analysis. The outcome does not seem consistent with ICANN’s prior decisions in similar cases. It should concern the Internet community that ICANN has shown itself to be much more susceptible to political pressure than its limited mandate would recommend.
Nevertheless, ICANN has now rendered a clear decision. This brings to a close a period Continue reading
