White Box Open Networking: A Cure for Your Regulatory Compliance Ills
Just about every major US regulatory requirement says companies must use software that’s fully supported by the vendor that sells it. Simply put, if you’re using software that is beyond its end of life, you’re not only posing a security risk to your company – you’re also out of regulatory compliance.
It’s an issue for any public company, given that they must all comply with the Sarbanes Oxley Act, as well as any company that must meet the Payment Card Industry Data Security Standard (PCI DSS) or the Health Insurance Portability and Accountability Act (HIPAA). Those three acts alone cover an awful lot of, if not most, US companies.
All software has a lifecycle, including the network operating system (NOS) software controlling all the network switches and routers in enterprise networks. When that NOS is nearing its end of life, meaning you have no choice but to upgrade in order to stay in compliance, it’s a good time to assess your available options. In fact, given the pace of technology change, it’s a safe bet that you’ve got alternatives that quite literally didn’t exist when you installed your current NOS five, six — or more — years ago.

Introducing ebpf_exporter
This is an adapted transcript of a talk I gave at Promcon 2018. You can find slides with additional information on our Prometheus deployment and presenter notes here. There's also a video.
Tip: you can click on the image to see the original large version.
Here at Cloudflare we use Prometheus to collect operational metrics. We run it on hundreds of servers and ingest millions of metrics per second to get insight into our network and provide the best possible service to our customers.
Prometheus metric format is popular enough, it's now being standardized as OpenMetrics under Cloud Native Computing Foundation. It's exciting to see convergence in long fragmented metrics landscape.
In this blog post we'll talk about how we measure low level metrics and share a tool that can help you to get similar understanding of your systems.
There are two main exporters one can use to get some insight into a Linux system performance.
The first one is node_exporter that gives you information about basics like CPU usage breakdown by type, memory usage, disk IO stats, filesystem and network usage.
The second one is cAdvisor, that gives similar metrics, but drills down to a container level. Instead Continue reading

Fixing My Twitter
It’s no surprise that Twitter’s developers are messing around with the platform. Again. This time, it’s the implementation of changes announced back in May. Twitter is finally cutting off access to their API that third party clients have been using for the past few years. They’re forcing these clients to use their new API structure for things like notifications and removing support for streaming. This new API structure also has a hefty price tag. For 250 users it’s almost $3,000/month.
You can imagine the feedback that Twitter has gotten. Users of popular programs like Tweetbot and Twitterific were forced to degrade client functionality thanks to the implementation of these changes. Twitter power users have been voicing their opinions with the hashtag #BreakingMyTwitter. I’m among the people that are frustrated that Twitter is chasing the dollar instead of the users.
Breaking The Bank
Twitter is beholden to a harsh mistress. Wall Street doesn’t care about user interface or API accessibility. They care about money. They care are results and profit. And if you aren’t turning a profit you’re a loser that people will abandon. So Twitter has to make money somehow. And how is Twitter supposed to make money in today’s Continue reading
The Internet Society and Global Scribes Work Together to Amplify Young Voices
On International Youth Day, the Internet Society and Global Scribes partnered to connect youth around the world to let their voices be heard, allowing them to become empowered and engaged global citizens, striving toward a more united and sustainable digital future.
As local and international actors innovate to solve the most pressing issues that we face in the world today, young people are often left out of the equation with little or no participation in important discussions and decision-making processes.
Youth across the world are often overlooked as a potential resource to solving global challenges, such as climate change, migration, health, and unemployment, despite being directly impacted by these issues and having opinions on how to solve them.
This also happens in the Internet ecosystem, where young people often do not have a place at the table when it comes to decisions that shape the Internet’s future.
While youth are recognized as “the future generation” and perceived as key to a more sustainable tomorrow, they are seldom given adequate platforms to let their voices be heard or allow them to contribute to their societies in a meaningful way, in their own right as youth.
Young people are often deprived of the opportunity to serve as catalysts for a more united and sustainable world Continue reading

AfPIF 2018 Day Three: Cloud Infrastructure, Local Content, and More
The growth of cloud infrastructure in Africa has been credited with the growth of local content in many regions, and it holds the key for Africa’s ability to attract content carriers and distribution networks.
The first panel of day three at the Africa Peering and Interconnection Forum (AfPIF) was dedicated to discussing the current scenario of cloud infrastructure and what it will take to grow the sector further, get the market interested, and eventually grow the level of content hosted locally.
South Africa has the most extensive cloud market, compared to other African countries, and it took concerted efforts from the different players, under the ISP Association, for the market to be deregulated and the laws to be put in place. The laws can take time, but industry players agree the laws are vital to investments in the market.
Although the industry may be small in Africa, cybersecurity is key, as businesses are susceptible to cybercrime, just like other global operators. That means the enactment of cyber security laws in the different countries, and continued training and awareness by industry players.
Power and cooling is another vital part, with many countries enjoying monopoly of power distribution. Liquid Telecom said Continue reading
