Last year I wrote about big disruptive outages on the T-Mobile and the CenturyLink networks. Those outages demonstrate how a single circuit failure on a transport route or a single software error in a data center can spread quickly and cause big outages. I join a lot of the industry in blaming the spread of these outages on the concentration and centralization of networks where the nationwide routing of big networks is now controlled by only a handful of technicians in a few locations. In early October, we saw the granddaddy of all network outages... more
The Google Fiber project is receiving international attention. This in itself is a good thing, since it brings the benefits of high-speed FttH infrastructure to the attention of large numbers of people in business and government who will not have to deal with such developments on a regular basis... At the same time we have to look at Google Fiber from the point of view of operating in the American regulatory environment. Yes, we can all learn from its disruptive model, and particularly when the results of the more innovative elements of the services begin to kick in; but for other reasons there is no way that this model can be replicated elsewhere. more
People have been trying to measure the global diffusion of the Internet and the digital divide between rich and poor nation for twenty five years. The first to do so was Larry Landweber, who noted whether or not a nation had an Internet (or other) connection. It was a binary metric -- yes or no -- and it was suitable to its time because there were only a handful of users who were restricted to teaching and research, using a few applications like email, file transfer, news groups and remote login. more
This was never part of the plan. Going into the Dubai World Conference on International Telecommunications (WCIT) two weeks ago, there was optimism aplenty. After weeks of online and media campaigning, proponents of a free Internet had managed to scare everyone into thinking that WCIT was tantamount to digital Armageddon. This had the effect of defusing the conference before it even started, or so it seemed... more
In spite of having a slow, expensive, government-controlled Internet infrastructure, Cuba is undergoing what Ted Henken and Sara Garcia Santamaria refer to as a digital revolution. The digital revolution might be said to have begun in 2007 when Yoani Sánchez launched her blog "Generation Y." Internet access was difficult -- she would get illegal connectivity at tourist hotels, and the blog was initially hosted in Germany. Soon, the Huffington Post began publishing her posts, and she has subsequently received many international awards, including the Ortega y Gasset Award for Digital Journalism in 2008. more
On June 12th, I speculated on Trump's forthcoming Cuba policy and its impact on the Internet. He outlined his policy in a June 16th speech and the Treasury Department published a FAQ on forthcoming regulation changes. It looks like my (safe) predictions were accurate. I predicted he would attack President Obama, brag about what he had done, make relatively minor changes that would not upset businesses like cruise lines, airlines, and telecommunication and hotel companies. more
A recent session of the Australian Computer Society (ACS) and the Australian Smart Communities Association (ASCA) masterclass on 5G, featured Dr. Ian Oppenheimer, the NSW Government's Chief Data Scientist and one of the country's most respected experts in radio technology. Ian is also the Chair of the scientific advisory board of the 6G Flagship organization, a global research organization based in Finland. This organization has just published a range of fascinating research papers on 6G. more
Want to easily show people where a specific submarine cable goes? Or what cables terminate in a particular location? Last year I wrote about Telegeography's cool interactive submarine cable map and how useful it is to understand the submarine cable side of Internet infrastructure. In that article I mentioned how great it would be if you could get a link for a particular cable or location that you could pass along to other people. more
How do we get more feedback from the operators of networks back into the standards process of the Internet Engineering Task Force (IETF)? How do we help know whether the open standards being developed within the IETF reflect the operational realities of the networks into which those standards will be deployed? If we could get more network operators participating in the IETF standards process, would that result in better standards that are deployed faster? more
The last few weeks have reinforced the importance of modern communication networks to societies. Health care providers, schools, governments, and businesses all rely on networks that enable us to connect and collaborate remotely. Had we encountered a similar pandemic ten years ago, we would not have been able to continue our activities on the level that is possible today. more
Deep Blue Cable is planning a Caribbean cable - phase one, the solid line shown on the map, bypasses Cuba but phase two shows two Cuban landing points. The phase two cities are not shown, but one appears to be near Havana and the other near Playa Girón. The phase one route survey is underway. Cable installation will begin in September 2018, and it is scheduled to be ready for service in December 2019. more
Once we decide that Network Neutrality is a good thing to (re)enshrine in law, then we need to ask how to do that effectively. One way would be to pass a law saying, "Thou shalt not discriminate." That's the current approach. But network operators will say that they must manage their network, and if, in the course of network management, they were to disadvantage some source, destination, application, service or content, they might be accused of violating the law. So any Network Neutrality law must have a Network Management Exception... more
In October 2020, I went on a two-week tour into Queensland's Outback, traveling through various landscapes from pastoral and agricultural lands to savanna and the desert. Leaving Brisbane, past Toowoomba, you enter the Darling Downs. This is one of the richest agricultural areas in Australia. British Botanist Alan Cunningham first explored it in 1827. However, only after the penal colony of Moreton Bay (now Brisbane) was closed, free settlers were allowed in the area. more
The Arctic region has largely been left out of the broadband arena in the past due to the high cost of building last-mile broadband infrastructure. The primary broadband available in the region has been provided for decades by Iridium Communications, which provided only low-bandwidth connections capable of supporting satellite phones and low-bandwidth monitoring devices. more
Yesterday's post explained how peer-to-peer (P2P) applications use the processing power, bandwidth, and storage capacity of participants in a service rather than centralized resources. This makes such applications generally less subject to catastrophic failure, much less subject to running out of resources (since each new user brings new capacity as well as new demand), and much cheaper FOR THE PROVIDER of the application in terms of hardware and bandwidth required. It's the FOR THE PROVIDER part that's the rub. Let's consider the case of BBC's iPlayer service... more
