Amid the global spread of COVID-19, the exceptional strict confinement to our homes offers important lessons about the urgency of bridging the digital divide.
Where I live, in Osona (rural Catalonia, northern Spain), 15 years ago there was no Internet access. Commercial operators said it wasn’t profitable. So, we set up a community network, Guifi.net, initially with radio connections, and in 2009 we deployed fiber optics. Today, we have connected many small towns and have more than 200,000 estimated users.
According to the National Statistical Institute, Osona County leads with the percentage of households with a computer: 82.5%, exceeding the Spanish average of 69.8%.
Connectivity has broken rural social isolation, connected our schools and hospitals, and it is helping people face this emergency situation. People can access multiple interactive channels to inform themselves without leaving home. Without connectivity, our confinement would feel like prison.
Connectivity has been an economic savior for us. In our livestock-driven region, robots milk cows that wear pedometers to measure their steps and detect diseases. Farmers use connected cameras to monitor whether their pigs have complications during birth. Technology has saved time, money, and improved productivity.
Just 15 years ago, Osona trailed Continue reading
Using ACLs for security vs compliance
Compliance exists in many forms, with tenancy, traffic isolation and access restriction. Compliance is mostly due to regulatory needs, which really comes down to security needs. Compliance applies to networking, fundamentally ensuring that resources can only be accessed from allowed locations. The actual media and content normally isn’t pertinent, as they merely just influence the scope of access for the data.
As a result, this post doesn’t delve into more complex compliance requirements such as deep packet inspection or encryption. Rather, this is to discuss how networking engineers use their existing toolset to enforce compliance requirements.
The most fundamental of these requests is networking access permissions. Most customers will allocate subnets for functional sections of their network.
ACLs are some of the most classic and undemanding forms of permission. The greatest part of ACLs is that they can be applied on nearly every networking device, and provide somewhat of a base level of security. But there are hidden complexities with ACLs that may not make it the ideal choice for most compliance solutions:
1. Connection State Tracking
ACLs are unidirectional elements, examining packets one at a time and only blocking traffic in a single direction. This can create some logical Continue reading
Cloudflare Doubling Size of 2020 Summer Intern Class
We are living through extraordinary times. Around the world, the Coronavirus has caused disruptions to nearly everyone's work and personal lives. It's been especially hard to watch as friends and colleagues outside Cloudflare are losing jobs and businesses struggle through this crisis.
We have been extremely fortunate at Cloudflare. The super heroes of this crisis are clearly the medical professionals at the front lines saving people's lives and the scientists searching for a cure. But the faithful sidekick that's helping us get through this crisis — still connected to our friends, loved ones, and, for those of us fortunate enough to be able to continue work from home, our jobs — is the Internet. As we all need it more than ever, we're proud of our role in helping ensure that the Internet continues to work securely and reliably for all our customers.
We plan to invest through this crisis. We are continuing to hire across all teams at Cloudflare and do not foresee any need for layoffs. I appreciate the flexibility of our team and new hires to adapt what was our well-oiled, in-person orientation process to something virtual we're continuing to refine weekly as new people join us.

MUST READ: Using BGP RPKI for a Safer Internet
As I explained in How Networks Really Work and Upcoming Internet Challenges webinars, routing security, and BGP security in particular remain one of the unsolved challenges we’ve been facing for decades (see also: what makes BGP a hot mess).
Fortunately, due to enormous efforts of a few persistent individuals BGP RPKI is getting traction (NTT just went all-in), and Flavio Luciani and Tiziano Tofoni decided to do their part creating an excellent in-depth document describing BGP RPKI theory and configuration on Cisco- and Juniper routers.
There are only two things you have to do:
- Read the document;
- Implement RPKI in your network.
Thank you, the Internet will be grateful.
The Mistake that Caused 1.1.1.3 to Block LGBTQIA+ Sites Today
Today we made a mistake. The mistake caused a number of LGBTQIA+ sites to inadvertently be blocked by the new 1.1.1.1 for Families service. I wanted to walk through what happened, why, and what we've done to fix it.
As is our tradition for the last three years, we roll out new products for the general public that uses the Internet on April 1. This year, one of those products was a filtered DNS service, 1.1.1.1 for Families. The service allows anyone who chooses to use it to restrict certain categories of sites.
Filtered vs Unfiltered DNS
Nothing about our new filtered DNS service changes the unfiltered nature of our original 1.1.1.1 service. However, we recognized that some people want a way to control what content is in their home. For instance, I block social media sites from resolving while I am trying to get work done because it makes me more productive. The number one request from users of 1.1.1.1 was that we create a version of the service for home use to block certain categories of sites. And so, earlier today, we launched 1.1.1. Continue reading
