Intel’s First Discrete Xe Server GPU Aimed At Hyperscalers
We have been waiting for years to see the first discrete Xe GPU from Intel that is aimed at the datacenter, and as it turns out, the first one is not the heavy compute engine we have been anticipating, but rather a souped up version of the Iris Xe LP and Iris Max Xe LP graphics cards that were launch at the end of October, which themselves are essentially the GPU extracted from the hybrid CPU-GPU “Tiger Lake” Core i9 processors for PC clients. …

Rate Limiting Questions? We have answers
As we have been implementing rate limiting on Docker Hub for free anonymous and authenticated image pulls, we’ve heard a lot of questions from our users about how this will affect them. And we’ve also heard a number of statements that are inaccurate or misleading about the potential impacts of the change. We want to provide some answers here to help Docker users clearly understand the changes, quantify what is involved, and help developers choose the right Docker subscription for their needs.
First let’s look at the realities of what rate limiting looks like, and quantify what is still available for free to authenticated Docker users. Anyone can use a meaningful number of Docker Hub images for free. Anonymous, unauthenticated Docker users get 100 container pull requests per six hours. And when a user signs up for a free Docker ID, they get 2X the quantity of pulls. At 200 pulls per six hours, that is approximately 24,000 container image pulls per month per free Docker ID. This egress level is adequate for the bulk of the most common Docker Hub usage by developers. (Docker users can check their usage levels at any time through the command line. Docker developer Continue reading
Real-time network telemetry for automation
The video discusses telemetry and requirements for network automation, providing an overview of sFlow measurement architecture and a discussion of recently added packet drop monitoring functionality, and ending with a live demonstration of GPU compute cluster analytics. The slides from the video are available here.
The video is part of recent talk Using Advanced Telemetry to Correlate GPU and Network Performance Issues [A21870] presented at the NVIDIA GTC conference.
New Features in MANRS Observatory: More Informative, Intuitive, and Easy to Use
In August 2019, the Internet Society supported the Mutually Agreed Norms for Routing Security (MANRS) initiative by creating a platform to visualize its members’ routing security data from around the globe. The MANRS Observatory’s interactive dashboard allows networks to check their progress in improving their routing security.
Last week, we updated some key features of the MANRS Observatory guided by member feedback. Below we share a summary of those changes.
Please note, detailed statistics and reports for specific networks are only available to MANRS participants. Your organization can become an MANRS member for free, and join a global group of people committed to making the Internet safer for us all. Find out how.
MANRS Observatory 3.0.1: Latest updates
- Shorter reporting cycle
- Improved favorite functionality
- Access to RIPEstat widget
- Change to how we round numbers
1. Shorter reporting cycle
Previously the MANRS Observatory provided status report updates up to 31 days after members’ had added their latest figures. While this wasn’t a real problem when looking at general trends, it was an issue for network operators who use the platform to check their network conformance. It was also an issue for the MANRS team, as we Continue reading
Network Automation Can Relieve Network Engineers Stretched Thin by Covid-19
The network has never been more vulnerable. Covid-19 has flung users out from the data center to home offices—where they are accessing critical systems, applications, and other users from unsecured devices and WiFi connections. As a result, it’s all hands on deck for IT, with network engineers deputized as IT support staff in a mad rush to give remote users fast and reliable, yet secure, access to the tools and information they need.
But what of the regular duties of these engineers? They are being pushed back in favor of new priorities—stretching network engineering resources, already spread thin, to the breaking point.
Enter network automation. VMware NSX-T allows organizations to automate and simplify operations in the age of Covid. Tasks that were once performed manually through the UI or CLI can now be automated with the NSX API—creating the foundation for dynamic, flexible and responsive network architectures that can support a world where users, devices, applications and data connect across private, public and hybrid cloud environments.
Networking professionals who want to learn more about how to automate operations should check out the following on-demand sessions from VMworld:

UK Black History Month at Cloudflare
In February 2019, I started my journey at Cloudflare. Back then, we lived in a COVID-19 free world and I was lucky enough, as part of the employee onboarding program, to visit our San Francisco HQ. As I took my first steps into the office, I was greeted by a beautiful bouquet of Protea flowers at the reception desk. Being from South Africa, seeing our national flower instantly made me feel at home and welcomed to the Cloudflare family - this memory will always be with me.
Later that day, I learnt it was Black History Month in the US. This celebration included African food for lunch, highlights of Black History icons on Cloudflare’s TV screens, and African drummers. At Cloudflare, Black History Month is coordinated and run by Afroflare, one of many Employee Resource Groups (ERGs) that celebrates diversity and inclusion. The excellent delivery of Black History Month demonstrated to me how seriously Cloudflare takes Black History Month and ERGs.
Today, I am one of the Afroflare leads in the London office and led this year’s UK Black History Month celebration. 2020 has been a year of historical events, which made this celebration uniquely significant. George Floyd’s murder Continue reading
Worth Reading: Protocol Options Rusted Shut
A long while ago I found a great article explaining TLS 1.3 and its migration woes on CloudFlare blog. While I would strongly recommend you read it just to get familiar with TLS 1.3, the real fun starts when the author discusses migration problems, kludges you have to use trying to fix them, less-than-compliant implementations breaking those kludges, and options that were supposed to be dynamic, but turn out to be static (rusted shut) due to middleboxes that implemented protocols as-seen-in-the-wild not as-described-in-RFCs.
Change a few TLAs and you could be reading about TCP, IP stack, IPv6, BGP… I addressed those aspects in the ossification and centralization part of Upcoming Internet Challenges webinar.

Exploring Vendor-Agnostic Extended Detection and Response
Extended Detection and Response (XDR) unifies data to truly detect threats in real-time and respond to them.Internet Insights – On Track for Launch
Things might have seemed quiet on our Measuring the Internet activities for the last few weeks, but lots of work has been taking place behind the scenes to ensure that the Internet Society’s Internet Insights platform will be ready for phase one of its launch in December 2020.
What We’re Working On
To help everyone gain deeper insight into the Internet, we’re consolidating trusted third-party Internet measurement data from various sources into a single platform – Insights. We’ll use this data to examine trends, generate reports, and tell data-driven stories. Insights will be available to everyone, everywhere so that anyone can better understand the health, availability, and evolution of the Internet.
Our Data Partners
Phase one of Insights will launch with an initial set of data that will help to illustrate two of our four focus areas: Internet Shutdowns and Enabling Technologies. We’re sharing data sourced from the following trusted third-party data providers and are working to integrate data from more organizations as the platform develops.
