When people pause the Internet goes quiet
Recent news about the Internet has mostly been about the great increase in usage as those workers who can have been told to work from home. I've written about this twice recently, first in early March and then last week look at how Internet use has risen to a new normal.
As human behaviour has changed in response to the pandemic, it's left a mark on the charts that network operators look at day in, day out to ensure that their networks are running correctly.
Most Internet traffic has a fairly simple rhythm to it. Here, for example, is daily traffic seen on the Amsterdam Internet Exchange. It's a pattern that's familiar to most network operators. People sleep at night, and there's a peak of usage in the early evening when people get home and perhaps stream a movie, or listen to music or use the web for things they couldn't do during the workday.
But sometimes that rhythm get broken. Recently we've seen the evening peak by joined by morning peaks as well. Here's a graph from the Milan Internet Exchange. There are three peaks: morning, afternoon and evening. These peaks seem to be caused by people working from Continue reading

Virtual eXtensible LANs -VXLANs
The tutorial discusses configuration of VXLANs on Arista vEOS and Openvswitch virtual machines. The VXLANs extend an L2 network by connecting VLANs from multiple hosts through UDP tunnels called VXLAN segments. VXLANs use Internet Protocol (both unicast and multicast) as the transport medium. VXLAN segments are identified by a 24-bit Virtual Network Identifier (VNI). Within […]Continue reading...

From Isolation to Preparedness and Empowerment in Rural Argentina
Nelso Rodríguez is a nurse and one of the founders of the community network in El Cuy, Patagonia, Argentina.
A little over a year ago, there was no Internet or mobile connection in my isolated town of El Cuy, population 540.
After several unsuccessful attempts by the provincial government to bring in satellite Internet – which was of very poor quality, at very high costs – our people began to demand an Internet for all.
After a newspaper article exposed our lack of connectivity, the Internet Society offered to help us set up a community network. There was a fiber-optic cable passing through a village just 50 kilometers away, which also had a tower with an Internet signal. So, a group of residents volunteered to dig the trenches for the anchors and lay the concrete. The Internet Society financed all the material and provided the technical expertise. After making a connection between two antennas, we managed to bring community Internet to El Cuy.
Our network has been up and running since February 2019, reaching almost 400 residents in El Cuy and another 100 in the nearby town of Cerro Policía. This has been spectacular in so many ways!

DDoS attacks have evolved, and so should your DDoS protection
The proliferation of DDoS attacks of varying size, duration, and persistence has made DDoS protection a foundational part of every business and organization’s online presence. However, there are key considerations including network capacity, management capabilities, global distribution, alerting, reporting and support that security and risk management technical professionals need to evaluate when selecting a DDoS protection solution.
Gartner’s view of the DDoS solutions; How did Cloudflare fare?
Gartner recently published the report Solution Comparison for DDoS Cloud Scrubbing Centers (ID G00467346), authored by Thomas Lintemuth, Patrick Hevesi and Sushil Aryal. This report enables customers to view a side-by-side solution comparison of different DDoS cloud scrubbing centers measured against common assessment criteria. If you have a Gartner subscription, you can view the report here. Cloudflare has received the greatest number of ‘High’ ratings as compared to the 6 other DDoS vendors across 23 assessment criteria in the report.
The vast landscape of DDoS attacks
From our perspective, the nature of DDoS attacks has transformed, as the economics and ease of launching a DDoS attack has changed dramatically. With a rise in cost-effective capabilities of launching a DDoS attack, we have observed a rise in the number of under 10 Gbps DDoS Continue reading
Empowering our Customers and Service Partners
Last year, Cloudflare announced the planned expansion of our partner program to help managed and professional service partners efficiently engage with Cloudflare and join us in our mission to help build a better Internet. Today, we want to highlight some of those amazing partners and our growing support and training for MSPs around the globe. We want to make sure service partners have the enablement and resources they need to bring a more secure and performant Internet experience to their customers.
This partner program tier is specifically designed for professional service firms and Managed Service Providers (MSPs and MSSPs) that want to build value-added services and support Cloudflare customers. While Cloudflare is hyper-focused on building highly scalable and easy to use products, we recognize that some customers may want to engage with a professional services firm to assist them in maximizing the value of our offerings. From building Cloudflare Workers, implementing multi-cloud load balancing, or managing WAF and DDoS events, our partner training and support enables sales and technical teams to position and support the Cloudflare platform as well as enhance their services businesses.
Training
Our training and certification is meant to help partners through each stage of Cloudflare adoption, Continue reading

Linux Network Observability: Building Blocks
As developers, operators and devops people, we are all hungry for visibility and efficiency in our workflows. As Linux reigns the “Open-Distributed-Virtualized-Software-Driven-Cloud-Era”— understanding what is available within Linux in terms of observability is essential to our jobs and careers.
Linux Community and Ecosystem around Observability
More often than not and depending on the size of the company it’s hard to justify the cost of development of debug and tracing tools unless it’s for a product you are selling. Like any other Linux subsystem, the tracing and observability infrastructure and ecosystem continues to grow and advance due to mass innovation and the sheer advantage of distributed accelerated development. Naturally, bringing native Linux networking to the open networking world makes these technologies readily available for networking.
There are many books and other resources available on Linux system observability today…so this may seem no different. This is a starter blog discussing some of the building blocks that Linux provides for tracing and observability with a focus on networking. This blog is not meant to be an in-depth tutorial on observability infrastructure but a summary of all the subsystems that are available today and constantly being enhanced by the Linux networking community for networking.
