Today's Weekly Show delves into DNS performance and endpoint testing with sponsor ThousandEyes. We'll review key findings from a new report on the state of global DNS authored by ThousandEyes, and discuss how to analyze performance and improve troubleshooting with end point testing.

I think we’ve reached peak bombshell report discussion at this point. It all started this time around with the big news from Bloomberg that China implanted spy chips into SuperMicro boards in the assembly phase. Then came the denials from Amazon and Apple and event SuperMicro. Then started the armchair quarterbacking from everyone, including TechCrunch. From bad sources to lack of technical details all the way up to the crazy conspiracy theories that someone at Bloomberg was trying to goose their quarterly bonus with a short sale or that the Chinese planted the story to cover up future hacking incidents, I think we’ve covered the entire gamut of everything that the SuperMicro story could and couldn’t be.
So what more could there be to say about this? Well, nothing about SuperMicro specifically. But there’s a lot to say about the fact that we were both oblivious and completely unsurprised about an attack on the supply chain of a manufacturer. While the story moved the stock markets pretty effectively for a few days, none of the security people I’ve talked to were shocked by the idea of someone with the power of a nation state inserting themselves into the supply chain Continue reading
Getting the best end-user performance from HTTP/2 requires good support for resource prioritization. While most web servers support HTTP/2 prioritization, getting it to work well all the way to the browser requires a fair bit of coordination across the networking stack. This article will expose some of the interactions between the web server, Operating System and network and how to tune a server to optimize performance for end users.
On Linux 4.9 kernels and later, enable BBR congestion control and set tcp_notsent_lowat to 16KB for HTTP/2 prioritization to work reliably. This can be done in /etc/sysctl.conf:
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr
net.ipv4.tcp_notsent_lowat = 16384
A single web page is made up of dozens to hundreds of separate pieces of content that a web browser pulls together to create and present to the user. The main content (HTML) for the page you are visiting is a list of instructions on how to construct the page and the browser goes through the instructions from beginning to end to figure out everything it needs to load and how to put it all together. Each piece of content requires a Continue reading
Imagine how much the Internet has changed our lives in the last few decades. Today, thanks to the Internet, we can communicate with anyone around the world, instantaneously, reliably and cheaply. This enables us not only to be close to our friends and family that may be far away but also to bridge the knowledge gap that we have with the developed world. It also opens many work opportunities that we wouldn’t even imagine just a few years back and democratize media, allowing anyone to reach instantaneously millions of people at almost no cost, forcing transparency in governance more than ever before.
At national level, our economies are benefiting from the economic opportunities, directly and indirectly related to the Internet. Experts say that this is just the tip of the iceberg and that there are many more opportunities that are yet to be discovered.
However, we cannot deny that the Internet also comes with increasing challenges. Cybercrime is endangering Internet users, organizations and even countries. Our privacies are threatened every day. And more … It is therefore appropriate that governments act to protect its citizens from the negatives impacts of the Internet by enacting laws and regulations. It was therefore Continue reading
Be mindful of these four areas of security when considering an SD-WAN solution. By incorporating security measures like these into an SD-WAN solution, businesses gain assurance that their data, network, IT assets, and customers are protected.

Is GIT any way related to Network Guys ? What is GIT and how a network engineers can benefit from It. Most of the network engineer might have not came across GIT and even not used in their work environment,But as mentioned in earlier posts that inclusion of DevOps in Networking has made network engineer to learn about automation and related technologies.
GIT is a distributed version control software that keeps track of every modification to the code. If any change or mistake is made , we can look back and compare with earlier version of code and find for any mistake.
So how GIT can be useful for Network Engineers ? Network Engineer can use GIT to see the config,how and when it got changed and who made the change ,all the changes in a file can be tracked easily.
Git can be easily installed by following the steps provided in link https://git-scm.com/book/en/v2/Getting-Started-Installing-Git

Automatic discovery of tactics in spatio-temporal soccer match data Decroos et al., KDD’18
Here’s a fun paper to end the week. Data collection from sporting events is now widespread. This fuels an endless thirst for team and player statistics. In terms of football (which shall refer to the game of soccer throughout this write-up) that leads to metrics such as completed passes, distance covered, intercepts, shots-on-goal, and so on. Decroos et al. want to go one level deeper though, and use the data to uncover team tactics. The state of the art today for tactical analysis still involves watching hours of video footage.
This paper focuses on the problem of detecting tactics from professional soccer matches based on spatio-temporal data.
Now when I think of tactics, a key component in my mind is the team shape and movement of players off the ball. Unfortunately Decroos et al., don’t have the data available to analyse that. So they have to do what they can based on more limited information.
Our dataset consists of event data for the English Premier League for the 2015/2016 season. This event data was manually collected by humans who watch video feeds of the matches Continue reading

Today is the 30th Anniversary of National Coming Out Day. We wanted to share some coming out stories from members of Proudflare and draw attention to resources the Human Rights Campaign provides to those who are thinking about coming out or wish to be supportive of those who come out to them.
On October 11, 1987, about 500,000 people marched on Washington for Lesbian and Gay Rights. This was the second demonstration of this type in the capital and it resulted in the formation of several LGBTQ organizations.
In the late 1980s, the LGBTQ community recognized that they often reacted defensively to anti LGBTQIA+ actions and the community came up with the idea of a national day for celebrating coming out. The anniversary of the 1987 march was chosen as that national day.
Each year on October 11th, National Coming Out Day continues to promote a safe world for LGBTQ individuals to live truthfully and openly.
