Behind the Curtain: Making IPv6 Work

Wouldn't it be nice if turning on IPv6 really was 'press one button and the rest is magic' easy? For some things, it is. If you're talking about client-side, enabling an IPv4-only home service on DSL or fibre really can be this simple, because all the heavy lifting is being done inside your ISP: you're not enabling IPv6 in the network, you're turning on the last mile. It was knocking at your door and you just had to let it in. more

Electricity Utilities and IoT

More and more connected devices will require more and better electricity solutions. In many developing economies more people have ready access to a smartphone and the internet than they have access to electricity. For that reason we have seen mobile telecoms operators starting to include power solutions (mainly through distributed energy systems, using solar panels) in order to sell more phones and telecom services. This shows how important access to electricity is. more

Mobile Broadband Penetration in Asia

The advent of mobile broadband triggered a huge change in broadband access across Asia. Following more than a decade of strong growth in almost all mobile markets in the region, an amazing transition to new generation mobile networks and services took place. By end 2014 there were a total of 1.2 billion mobile subscribers and with annual growth running at over 40% coming into 2015 the numbers were expected to hit 1.7 billion by end-2015. more

Broadband Carrier Quandary: Exploit Bandwidth Scarcity, or Reduce It?

Comcast enhanced the value position of its broadband subscriptions by increasing the monthly data allowance to 1 Terrabyte (1000 Gigabytes). See Comcast Announcement. As an independent, unsponsored researcher, I can say "Thank You Comcast" without adverse consequences and only a bit of irony. This company does much to displease, but an expanded data allowance offers a winning proposition. more

Rebalancing Telco Infrastructure Investments

One of the reasons telecommunications has been so successful for more than 160 years is that it adopted a strategy that resulted in a seamless network all around the world. You can pick up a phone anywhere in the world and, with little or no instruction, make a call to anybody else in the world without worrying what phones and technology they are using on the other end of the line... But during that process the nature of the network operators changed. more

US Telcos Withdrawing from DSL and Telephony Markets - A Case of Lobbying Power and Poor Regulation

During the last few months the US's main DSL providers AT&T and Verizon have begun retracting from the DSL and landline market in many rural and less commercially viable areas while concentrating on their wireless LTE ambitions. DSL and voice telephony provide relatively low returns, which can be whittled away through network maintenance costs, while LTE promises to deliver proportionately higher profits, based on exorbitant charges by data volume.  more

The Internet and My 53 Years Online

With the upcoming celebration of the 50 years of the Internet, I'm trying to figure out how the traditional story misses the powerful idea that has made the Internet what it is -- the ability to focus on solutions without having to think about the network or providers. It's not the web -- thought that is one way to use the opportunity. The danger in a web-centric view is that it leads one to make the Internet better for the web while closing the frontier of innovation. more

Complete Internet Shutdown Reported in Syria

While Syria's Internet disruptions in the recent past have been linked to Government's efforts to prevent cheating during national high school exams, today's complete Internet shutdown reported by Dyn Research is unknown and does not appear to be exam-related. more

DNS Complexity Lessons

Recently, Bert Hubert wrote of a growing problem in the networking world: the complexity of DNS. We have two systems we all use in the Internet, DNS and BGP. Both of these systems appear to be able to handle anything we can throw at them and "keep on ticking." But how far can we drive the complexity of these systems before they ultimately fail? Bert posted a chart on the APNIC blog to illustrate the problem. more

The Lean and Antifragile Data Centre

Cloud is a new technology domain, and data centre engineering is still a developing discipline. I have interviewed a top expert in cloud infrastructure, Pete Cladingbowl. He has a vision of the 'lean' data centre and a better kind of Internet for users to reach it. He also has a roadmap for how these can be practically realised. The key is to apply established theories of value flow from more mature industries. more

Some Random Notes from IETF 115

The IETF held its 115th meeting in London in November 2022. This was another in the set of hybrid meetings with specific support for online attendees in addition to the normal face-to-face meetings for the week. In no particular order, here are a few of my impressions from the IETF meeting. more

Cutting Through the Twitter DDoS Hype

There are a lot of theories flying around about why Twitter and other social media services got knocked offline yesterday. I've heard rumors about it being linked to political tension between Georgia and Russia. Others blame Iran for the outages. I'm not a political commentator, therefore I cannot comment on anyone's political views -- but I have some logic and common sense, and I can draw some objective conclusions. more

Microsoft Launches AI-driven’ Security Copilot’ to Help Companies Fight Hacking Attempts

Microsoft continues to integrate new artificial intelligence technology into its products and today announced a cybersecurity "copilot" to help companies track and defend against hacking attempts. This tool is part of Microsoft's attempt to dominate the fast-growing field of "generative" AI. more

Tracking Outages

The idea of tracking data outages spawned from an early discussion on the outages forum including feedback from an outages survey about having a status page for (un)planned outages as a central resource. The purpose of such effort is to have a wider focus that one could view as opposed to having to check dozens of provider status pages. There were many ideas put forth but nothing really panned out and things kinda fell on the back burner. more

The Year 2038 Computer Problem – a Repeat of Y2K?

The Year 2038 Problem relates to representing time in many digital systems as the number of seconds passed since 00:00:00 UTC on 1 January 1970 and storing it as a signed 32-bit integer. Such implementations cannot encode times after 03:14:07 UTC on 19 January 2038. At that time, systems might crash and be unable to restart when the time is changed to that date. It is like the Y2K problem caused by the widespread use of two decimal digits to store the year. While that problem was overhyped... more
