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.

A Brief Look at the Domain Attack Surface of Streaming Media Companies

The term "attack surface" is often heard in cybersecurity conversations. It refers to the sum of all possible attack vectors or the vulnerabilities that threat actors can exploit to penetrate a target network or damage an organization somehow. An unused and forgotten subdomain, for instance, can become an attack vector when taken over. Certain categories of companies have very large attack surfaces. Such is the case of streaming media businesses like Netflix and HBO Max.

A Look at DNS Trends and What the Future May Hold

We used to think of computer networks as being constructed using two fundamental common infrastructure components: names and addresses. Every connected device had a stable protocol address to allow all other devices to initiate a communication transaction with this device by addressing a data packet to this protocol address. And every device was also associated with a name, allowing human users and human use applications to use a more convenient alias for these protocol addresses.

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.

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...

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.

Scaling the Root of the DNS

The DNS is a remarkably simple system. You send it queries, and you get back answers. Within the system, you see exactly the same simplicity: The DNS resolver that receives your query may not know the answer, so it, in turn, will send queries deeper into the system and collects the answers. The query and response process is the same, applied recursively. Simple. However, the DNS is simple in the same way that Chess or Go are simple...

Beyond the Interweb

Today's Internet is a network of networks and seen through the lens of the web. We need to look beyond the engineering history to see the Internet in the context of the broader vision of JCR Licklider, an acoustic psychologist, and his vision of man/computer symbiosis... JCR Licklider would've been thrilled to see such a powerful man-machine symbiosis becoming so normal and having it work so well. Lick, as he was called, can be considered the grandfather of the Internet.

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."

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.
