Could SNET Become Cuba’s Guifi.net?

In an earlier post, I described Havana's community network, SNET, and wondered what it could become if the government and ETECSA were willing to legitimatize and support it. Spain's Guifi.net provides a possible answer to that question. Guifi.net is said to be the largest community network in the world. It began in 2004 and has grown to have 34,165 nodes online with 16,758 planned, 407 building, 612 testing and 4,043 inactive. more

Call for Participation - DNSSEC Workshop at ICANN 54 in Dublin, Ireland

RIPE 75: Imprssions of the Meeting

RIPE held its 75th meeting in Dubai in mid-October. As usual, there was a diverse set of presentations covering a broad range of activities that are taking place on today's Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centers, IPv6, the DNS, routing and network measurement. If that's not enough, the topic of the Internet of Things has been added as a Working Group in the RIPE pantheon. If you add address policy, database and RIPE services to the mix, you get a pretty packed five days with topics that would appeal to most Internet folks. more

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... 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

Telcos Cannot Wind Back the Clock

The proposals by the European and Arab telcos that are being considered at the World Conference on International Telecommunications (WCIT) conference in Dubai later this year are most certainly facing defeat. This is not because the USA believes that the international telecommunications regulations (ITR) cannot be discussed by the ITU. America has a rather strange set of national regulations in which they have combined internet infrastructure and content -- and as such they claim that this no longer has anything to do with telecommunications. more

Global Spam Levels Drop Following Certain Events

If you haven't noticed lately, spam levels around the world have started dropping especially in October after a couple of events occurred. The first is a Russian crackdown on alleged spam king Igor Gusev, thought to be involved in the operations of SpamIt.com. SpamIt mysteriously shut down in late September, perhaps because Gusev caught wind of law enforcement starting to take notice of him. more

From Net Neutrality to Seizing Opportunity

Network neutrality is important in the context of assuring the opportunity to innovate in how we communicate and connect. We can't define it in terms of specific outcomes but rather in terms of what we enable. The Internet is just one example of what we can do when given the opportunity to use software to fashion our own solutions... I thought about this more when I found myself in my hospital room (after knee surgery) unable to open and close the shades by myself. But yet I could control the lights in my house! more

Big Internet Outages - There Is No Such Thing as a Routine Software Upgrade

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

45th Anniversary of the First Message Between ARPAnet Computers

Given that CircleID is about "Internet Infrastructure" it would be remiss if there wasn't a mention here that October 29, 2014, was the 45th anniversary of the moment when the first message was sent between two ARPAnet computers located at UCLA and the Stanford Research Institute (SRI). That moment was chronicled well this year by Matt Novak writing on Gizmodo's Paleofuture, complete with photos of the original logs and more. more

How the Clinton “Village” Transformed Internet Paradigms: Together Making a Difference

U.S. Presidential elections and the resulting Administrations can make an enormous difference on many levels and become profound points of inflection. This reality is certainly starkly visible today. Perhaps for the Internet community as well as the general public, some of the largely unknown events and actions surrounding the Internet and the Clinton team from 25 years ago can provide a basis for engagement over the coming months. more

Cisco: Africa in 2017 to Have More Internet Users Than U.S.

Carlos Slim of Telmex tells me the world is about to change. "Two billion more people will connect to the Internet when smartphones cost $50. The phone makers are promising me a $50 phone in 2014." If Spreadtrum and Firefox deliver a $25 smartphone, as promised, that could accelerate takeover. ~310,000,000 Africans will be connected to the Internet in 2017, Arielle Sumits of Cisco predicts... It's inevitable that the U.S. will be dwarfed by the rest of the world. more

Iranian Protesters Urged Not to DDoS Gov Sites, Could Backfire as Country’s Networks Are Centralized

In the midst of heavy demonstrations in the street of Iran against current regime and controversial election results, online activist have began organizing online attacks against government websites. Activists are asking supporters to use tools currently being spread via Twitter, Facebook, and other social networking sites to participate in the attack. However as one blogger writes, the attack might in fact back fire in a country like Iran where network infrastructure is relatively centralized... more

Getting on with Digital Transformation: Three Steps to Making Strategic Technology Choices

In a recently published Uptime Institute Survey, Uptime Institute found that organizations operating data centers are finding it increasingly difficult to recruit professionals skilled in security, networking, and hybrid technologies. This realization comes at an interesting time, as the monolithic business infrastructure built over the last two decades is now entering a period of transformation. more

U.S. Outgunned in Hacker War

The Wall Street Journal has an interview with the outgoing head of the FBI's cyber crime investigation Shawn Henry. In it, he has a blunt assessment of the US's capabilities when it comes to combatting online crime, especially data theft and hacking... The more I read around the Internet, the more clear it's becoming at how cyber security is becoming a central focus. This has pretty big implications for the cloud. more
