Let’s Not Forget About Solar Flares

As the world becomes more and more reliant on electronics, it's worth a periodic reminder that a large solar flare could knock out much of the electronics on earth. Such an event would be devastating to the Internet, satellite broadband, and the many electronics we use in daily life. A solar flare is the result of periodic ejections of matter from the sun into space. Scientists still aren't entirely sure what causes solar flares, but they know that it's somehow related to shifts in the sun's magnetic field. more

An IPv6 Update for 2020

The Australian Domain Name Administration, AUDA, recently published its quarterly report for the last quarter of 2020. The report contained the interesting snippet: "The rapid digitization of our lives and economy -- necessitated by COVID-19 -- continued to underpin strong growth in .au registrations. New .au domains created in December 2020 were up 23 percent from December 2019, while total domains under management were up more than 2.1 percent over the same period." more

The Netizen’s Guide to Reboot the Root (Part II)

The first part of this series explained how Amendment 35 to the NTIA-Verisign cooperative agreement is highly offensive to the public interest. But the reasons for saving the Internet are more fundamental to Western interests than a bad deal made under highly questionable circumstances. One of the world's foremost experts on conducting censorship at scale, the Chinese Communist Party's experience with the Great Firewall... more

The Christmas Goat and IPv6 (Year 11)

This is the fourth year now with almost no snow during the Christmas Goat event here in Sweden, and so once again, you get a photo without any snow. Because of Covid-19 and 99.99% people working for home, I have not even seen the Goat live this year... What a crazy year it has been! more

Unintended Consequences of Submarine Cable Deployment on Internet Routing

The network layer of the Internet routes packets regardless of the underlying communication media (Wifi, cellular telephony, satellites, or optical fiber). The underlying physical infrastructure of the Internet includes a mesh of submarine cables, generally shared by network operators who purchase capacity from the cable owners. As of late 2020, over 400 submarine cables interconnect continents worldwide and constitute the oceanic backbone of the Internet. more

DNS Oblivion

Technical development often comes in short, intense bursts, where a relatively stable technology becomes the subject of intense revision and evolution. The DNS is a classic example here. For many years this name resolution protocol just quietly toiled away. The protocol wasn't all that secure, and it wasn't totally reliable, but it worked well enough for the purposes we put it to. more

Protecting an Enterprise from Cyber Catastrophe

We are suffering an epidemic of cyberattacks while in a viral pandemic. This post is for those who have responsibility for assuring that the IT-based services offered by their enterprise can quickly recover in the case of successful cyber-attack or other disaster. University of Vermont Medical Center (UVMMC) is an excellent hospital. I owe my life to treatment there and am grateful for both the skill and the kindness of UVMMC staff. They have been devastated by a cyber-attack. more

Cybersecurity Considerations in the Work-From-Home Era

Verisign is deeply committed to protecting our critical internet infrastructure from potential cybersecurity threats, and to keeping up to date on the changing cyber landscape. Over the years, cybercriminals have grown more sophisticated, adapting to changing business practices and diversifying their approaches in non-traditional ways. We have seen security threats continue to evolve in 2020, as many businesses have shifted to a work from home posture due to the COVID-19 pandemic. more

The End of Broadband Networks as We Know Them

A group of major telecommunications companies -- Vodafone, BT, Telefonica and Deutsche Telekom -- recently announced something a bit unexpected. In the Open BNG Operator Position Paper, they call for a fundamental, industry-wide change to the way broadband networks are built. Specifically, they advocate for collaboration throughout the telco world, with a convergence around open broadband network gateways (BNGs). more

Network Outages Go Global

On August 30, CenturyLink experienced a major network outage that lasted for over five hours and disrupted CenturyLink customers nationwide as well as many other networks. What was unique about the outage was the scope of the disruptions as the outage affected video streaming services, game platforms, and even webcasts of European soccer. more

IoT From a Network Perspective: Learning to Navigate the New Realms

Let's play the analogy game. The Internet of Things (IoT) is probably going end up being like... a box of chocolates, because you never do know what you are going to get? a big bowl of spaghetti with a serious lack of meatballs? Whatever it is, the IoT should have network folks worried about security. Of course, there is the problem of IoT devices being attached to random places on the network, exfiltrating personal data back to a cloud server you don't know anything about. more

5G/F5G Cloud Announcements: NFV Game-Changing Confirmations

Over the past few days, Microsoft made two major announcements. One was a "playbook [for] providing a carrier-grade platform for edge and cloud computing to help network operators realize the full potential of 5G technology" using its it Azure cloud data centres. The second announcement was a new platform that enables satellite-based access to those same cloud data centres designated Azure Orbital. Coupled with these announcements was another one by Samsung... more

Your AI Strategy Canvas: Part 1

As the final project of my UC Berkeley School of Information course in Artificial Intelligence strategies, we had to submit an AI strategy canvas. Today, I will attempt to share important aspects of the canvas, so you and your team may have a template to work from and consider. Let's begin. We will look at both a strategy and operations perspective both internally and externally. Part one will include Internal and Operational Strategies, while Part II will examine external processes, threats, and procedures. more

Is the Internet Sustaining the Growth Trajectories Observed as the COVID-19 Pandemic Hit the World?

With the COVID-19 pandemic hitting the fifth month of global disruption, many companies have readily shared data, statistics and observational insights on how the pandemic has impacted the global data infrastructure. At DE-CIX, we quickly observed core Internet infrastructure demand increasing and readily reported this data in April of 2020. Microsoft's CEO Satya Nadella remarked to DatacenterDynamics in April of 2020 "we have seen two years' worth of digital transformation in two months." more

Internet of Things Requires a Rethink of Business Models

There certainly is a lot of interest in machine-to-machine communication (M2M) and the Internet of Things (IoT). But what we are seeing is only what is happening on the surface. Most of the M2M activities are taking place unnoticed. For example, most newly produced electronic devices are now all M2M enabled. Over 100 million smart meters have already been deployed by the electricity industry, with literally hundreds of millions of them in the pipeline. Healthcare is another key industry. more
