An Opinion in Defence of NATs

Network Address Translation has often been described as an unfortunate aberration in the evolution of the Internet, and one that will be expunged with the completion of the transition of IPv6. I think that this view, which appears to form part of today’s conventional wisdom about the Internet unnecessarily vilifies NATs. In my opinion, NATs are far from being an aberration, and instead I see them as an informative step in the evolution of the Internet, particularly as they relate to possibilities in the evolution of name-based networking. Here’s why.

AfPIF 2017 Kicks Off In Abidjan

The annual Africa Peering and Interconnection Forum (AfPIF) kicked off at the Azalai Hotel in Abidjan, Ivory Coast. The first day is known as “Peering Coordinators Day” where peering managers from various networks, operators, and policy makers meet and deliberate on the various ways to exchange content locally, lower the cost of connectivity, and increase the number of internet users in the region. In the course of the three days, participants get a chance to discuss, exchange ideas, and agree to exchange content, known as peering. Most peering agreements are through the handshake and AfPIF encourages participants to take advantage of the various social events and share contacts. There is a session at the beginning and end of every day, where participant share their AS numbers, peering policy, and contacts, allowing those willing to interconnect to reach out. The first session explored the general data and interconnection landscape; Telegeography presented the latest statistics, which is derived from its annual survey. Statistics show that the growth of submarine cables has led to growth in Internet bandwidth and local content. Five years ago, International transit was growing at 40 per cent, but this year, the growth is at 30 per cent, owing Continue reading

Going Global – a Localization Case Study at Cloudflare

Today Cloudflare serves nearly 10% of all global internet requests and more than 80% of our customers are based outside of the United States. Cloudflare is rapidly growing and there is nothing more important to us than being able to better serve our users across the world beyond our global offices in San Francisco, Austin, Champaign, Washington D.C., New York, London, and Singapore.

Earlier this year, we launched a team to focus on global expansion and growth. In June, we presented our agile global market expansion experiment framework at LocWorld Barcelona and wanted to report back on how things were going.

Getting started

"If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart" – Nelson Mandela

At Cloudflare, we are motivated by our users from all around the world. Of our top 15 countries by traffic volume, 10 have official languages other than English. As a large part of our users do not speak our primary language of business, our priority is to reach and engage with these users in their native languages through localization.

As a growing company, Continue reading

IGF-USA: Promoting a More Inclusive Internet

The IGF-USA took place in Washington D.C on July 24, 2017. During the event, the panel "Promoting a More Inclusive Internet" looked at current barriers to an inclusive Internet and explored how access could be expanded to underserved areas and to underrepresented communities. Moderated by Dr. Brandie Nonnecke, Research & Development Manager for CITRIS and the Banatao Institute at the University of California-Berkeley and Chair of the San Francisco-Bay Area Internet Society Chapter Working Group on Internet Governance, the panel brought together several experts on access provision, each with many years experience of connecting the unconnected in the USA and overseas.

Ukraine Leaks Russian Social Media Ban

Another development in the long-running conflict between Ukraine and Russia occurred in May of this year when Ukrainian President Petro Poroshenko enacted a ban on Russia’s four most prominent internet companies in the name of national security.  The ban included the two most widely used social media websites, VKontakte (often referred to as the “Russian Facebook“) and Odnoklassniki (“Classmates” in Russian), as well as email service provider Mail.ru and Russian search engine Yandex.

These websites have such a significant Ukrainian user base that Mail.ru says it expects to lose $13 million this year as a result of the ban and Yandex is appealing the ban through Ukraine’s Supreme Administrative Court.

And now it appears that this ban has spilled out into the global routing table.  On 27 July 2017, Ukrainian ISP UARNet (AS3255) began announcing several new BGP routes that were hijacks of the IP address space of these Russian internet companies.  On this day, AS3255 briefly announced more-specific hijacks of each of these four Russian internet companies including 94.100.180.0/24 (Mail.ru), 87.250.250.0/23 (Yandex), 87.240.165.0/24 (Vkontakte) and 217.20.159.0/24 (Odnoklassniki).  While Continue reading

Get ready for new storage technologies and mediums

In a push to improve storage density, new, oblong-shaped solid-state drives (SSDs) are coming from Intel by the end of the year, the company has announced. It’s just one of a bunch of new memory forms and technologies that we’ll be seeing in due course, though.Intel’s “ruler” style drives are designed to slip neatly into a standard rack. The concept abandons the premise that memory products should look like traditional magnetic hard disc drives (HDDs) or Peripheral Component Interconnect Express (PCIe) expansion cards.To read this article in full or to leave a comment, please click here
