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

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

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

Know Someone Who Has Made the Internet Better? Postel Service Award Nominations Deadline May 15

Do you know of someone who has made the Internet better in some way who deserves more recognition? Maybe someone who has helped extend Internet access to a large region? Or wrote widely-used programs that make the Internet more secure? Or maybe someone who has been actively working for open standards and open processes for the Internet? 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

Do-It-Yourself Rural Fiber

Necessity has led Cubans to become do-it yourself (DIY) inventors -- keeping old cars running, building strange, motorized bicycles, etc. They've also created DIY information technology like software, El Paquete Semanal, street nets and WiFi hotspot workarounds. Last June the International Telecommunication Union (ITU) adopted a standard for "low-cost sustainable telecommunications infrastructure for rural communications in developing countries," L.1700. L.1700 cable should be of interest to both DIY technologists and ETECSA. more

Be Agile or Be Edged Out: “Live” from TM Forum 2017

I like a conference that's "Live". Not just a lively crowd coalescing together to passionately discuss and debate matters of common interests, but more so in the sense of physical presence: things you can feel and touch. In the case of the TM Forum Live! 2017 event, held last week at Nice, France, it's the Catalyst Pavilions where innovative solutions, best practices, and even exploratory experimentations were on full display. Do I mean that for an IT Operation Support Systems (OSS) and Business Support Systems (BSS) trade show, you can touch it? Yep. more

The Over-Optimization Meltdown

In simple terms, Meltdown and Spectre are simple vulnerabilities to understand. Imagine a gang of thieves waiting for a stage coach carrying a month's worth of payroll. There are two roads the coach could take, and a fork, or a branch, where the driver decides which one to take. The driver could take either one. What is the solution? Station robbers along both sides of the branch, and wait to see which one the driver chooses. 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

Making Internet Faster: Google, OpenDNS and Others Announce Joint Effort

Google, OpenDNS, content delivery networks and other operators have announced a joint effort called "The Global Internet Speedup," to "make the Internet faster". According to the group, this collaboration will be executed via an open IETF proposed standard called "edns-client-subnet" in order to help better direct content to users thereby decreasing latency, decreasing congestion, increasing transfer speeds and helping the Internet to scale faster and further. more

Spanish Joint-Network Investment in FttH Seeing Returns

Spain's economic anguish has had a number of repercussions for the country's telcos, with stable or declining revenue causing much nervousness as operators struggle to fund essential investment in spectrum and both fixed-line and mobile networks. Earlier this year Vodafone felt the pinch, announcing plans to cut its Spanish workforce by up to 1,000. Though general economic conditions have not helped, the move partly resulted from its own decisions. The company saw revenue drop for several quarters and so decided to save money by cutting handset subsidies. more

Don’t Blame Open Recursives For DDoS Attacks and Why You Should Implement BCP38

There has been plenty of buzz and chatter on the Internet recently concerning a very large DDoS attack against CloudFlare, with coverage on their blog, the New York Times, and the BBC, among many others. While attacks of this nature are certainly nothing new, the scale of this attack was surprising, reported to hit 120Gbps. For a sense of scale, your average cable modem is only about 20Mbps, or about 0.016% of that bandwidth. 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

Edward Mc Nair, executive director of the North American Network Operators Group (NANOG), delivered the keynote at the seventeenth regional meeting of the Caribbean Network Operators Group (CaribNOG), held from April 10 to 12 at the Hilton in Bridgetown, Barbados. McNair's keynote focused on the important role that network operator groups, or NOGs, play in building an Internet that serves the specific needs of the people in the region. more
