Consistent with our mission to “help build a better Internet,” Cloudflare believes that one of the most important roles for the Internet is to empower marginalized voices that may not be heard, or bring together oppressed groups of people that may otherwise find themselves isolated and alone. Six years ago, Cloudflare started Project Galileo to provide free services to vulnerable nonprofits, journalism and independent media voices online who might otherwise be in danger of being silenced by cyberattacks. Much has changed in the past couple of months as the COVID-19 pandemic has transformed the world while the United States faces a wave of protests addressing racial violence and inequality. These events have put further strain on vulnerable groups working in these spaces, and we have seen many organizations step up to ensure that those who are most affected by these circumstances are protected. At Cloudflare, we believe that protecting these groups from attack is essential to helping build a better Internet.
We are excited to mark the 6th anniversary of the project this month, and it is a good time for us to reflect, talk to participants, and see how the Project has grown and changed over the course of Continue reading
Example: Fully-Automated AWS Network Infrastructure Deployment
Regular readers of my blog probably remember the detailed explanations Erik Auerswald creates while solving hands-on exercises from our Networking in Public Cloud Deployments online course (previous ones: create a virtual network, deploy a web server).
This time he documented the process he went through to develop a Terraform configuration file that deploys full-blown AWS networking infrastructure (VPC, subnets, Internet gateway, route tables, security groups) and multiple servers include an SSH bastion host. You’ll also see what he found out when he used Elastic Network Interfaces (spoiler: routing on multi-interface hosts is tough).
Listen to the Hedge Podcast 39 to Learn about the Open Standards Everywhere Project
What is our Open Standards Everywhere (OSE) project all about? How did it get started? What are the project goals? What are some of the challenges web server operators face? How can we work together to make web servers more secure and available?
Recently Russ White and his team interviewed me on The Hedge Podcast Episode 39 to discuss all these questions and much more. I’ve known Russ for a good number of years and it was fun to talk with him and his co-hosts Eyvonne Sharp and Tom Ammon about all things related to the OSE project. I hope you enjoy listening to the episode as much as we enjoyed having the conversation!
I would encourage you to listen to some of the other Hedge podcast episodes, too, as they have some great content. A few I personally enjoyed included: episode 37 about DNS privacy; episode 31 about network operator groups (NOGs); and episode 30 with Ethan Banks from the Packet Pushers Network about why understanding the fundamentals of networking is so important.
Thank you to Russ, Eyvonne, and Tom for having me on the show!

The increased rate of change in networking isn’t just impacting the operational models used to run networks. Network security posture, infrastructure, and operations are having to adapt quickly as well. In this episode we sit down with Henry Jiang, CISO of Diligent Corporation, to talk about how security is adapting to current infrastructure trends.

High Availability Load Balancers with Maglev
Background
We run many backend services that power our customer dashboard, APIs, and features available at our edge. 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.
Previously, all traffic for these backend services would pass through several layers of stateful TCP proxies and NATs before reaching an available instance. This solution worked for several years, but as we grew it caused our service and operations teams many issues. Our service teams needed to deal with drops of availability, and our operations teams had much toil when needing to do maintenance on load balancer servers.
Goals
With the experience with our stateful TCP proxy and NAT solutions in mind, we had several goals for a replacement load balancing service, while remaining on our own infrastructure:
- Preserve source IPs through routing decisions to destination servers. This allows us to support servers that require client IP addresses as part of their operation, without workarounds such as X-Forwarded-For headers or the PROXY TCP extension.
- Support an architecture where backends are located across many racks and subnets. This prevents solutions that cannot Continue reading
How Should Network Architects Deal with Network Automation
A network architect friend of mine sent me a series of questions trying to figure out how he should approach network automation, and how deep he should go.
There is so much focus right now on network automation, but it’s difficult for me to know how to apply it, and how it all makes sense from an Architect’s PoV.
A network architect should be the bridge between the customer requirements and the underlying technologies, which (in my opinion) means he has to have a good grasp of both as opposed to fluffy opinions glanced from vendor white papers, or brushed off so-called thought leaders.
MANRS Fellowship Program Now Open
The first-ever MANRS (Mutually Agreed Norms for Routing Security) Fellowship Program is now accepting applications. If you are an emerging leader eager to improve the well-being of the Internet’s global routing system, apply now.
The program gives highly motivated individuals the chance to work alongside MANRS ambassadors, who are industry leaders participating in the Ambassador Program. Together, they will train diverse communities on good routing practices, analyze routing incidents, research into ways to secure routing, and survey the global policy landscape.
Fellows will improve their skills and bring new perspectives and ideas to MANRS. They will also gain valuable insights and networking opportunities from well-respected professionals called MANRS Ambassadors under the MANRS Ambassadors Program. The selection process for this program is currently underway.
The Internet Society supports this program as part of its work to reduce common routing threats and establish norms for network operations.
You can apply for a fellowship in three different areas: training, research, and policy. Each fellow will receive a stipend of $750 a month. There is no age requirement and you can apply for more than one category but will only be selected for one of them.
