Organizations can save money by negotiating better deals on a common piece of network equipment, analysts say.

QWERTYUIOP
— Text of the first email ever sent, 1971
The ARPANET (a precursor to the Internet) was created “to help maintain U.S. technological superiority and guard against unforeseen technological advances by potential adversaries,” in other words, to avert the next Sputnik. Its purpose was to allow scientists to share the products of their work and to make it more likely that the work of any one team could potentially be somewhat usable by others. One thing which was not considered particularly valuable was allowing these scientists to communicate using this network. People were already perfectly capable of communicating by phone, letter, and in-person meeting. The purpose of a computer was to do massive computation, to augment our memories and empower our minds.
Surely we didn’t need a computer, this behemoth of technology and innovation, just to talk to each other.
The history of computing moves from massive data processing mainframes, to time sharing where many people share one computer, to the diverse collection of personal computing devices Continue reading
Back in May last year, one of my colleagues blogged about the introduction of our Python binding for the Cloudflare API and drew reference to our other bindings in Go and Node. Today we are complimenting this range by introducing a new official binding, this time in PHP.
This binding is available via Packagist as cloudflare/sdk, you can install it using Composer simply by running composer require cloudflare/sdk
. We have documented various use-cases in our "Cloudflare PHP API Binding" KB article to help you get started.
Alternatively should you wish to help contribute, or just give us a star on GitHub, feel free to browse to the cloudflare-php source code.
PHP is a controversial language, and there is no doubt there are elements of bad design within the language (as is the case with many other languages). However, love it or hate it, PHP is a language of high adoption; as of September 2017 W3Techs report that PHP is used by 82.8% of all the websites whose server-side programming language is known. In creating this binding the question clearly wasn't on the merits of PHP, but whether we wanted to help drive improvements to the developer experience for Continue reading
Class is in session! This week, we are excited to announce that the new networking how-to video series is live on the Cumulus Networks website. Join our highly-qualified instructors as they school you on everything you need to know about web-scale networking. No backpack or homework required — learn everything you need from the comfort of your couch.
So, what’s on the syllabus for web-scale 101?

After watching these how-to video tutorials, you’ll be a web-scale scholar!
These video tutorials cover topics such as:
What’s the difference between configuring IP addresses with Juniper or Cumulus Linux? We’ll let you decide that for yourself. Head over to our how-to video page and begin your educational journey. No need to worry about tuition — this priceless educational experience is Continue reading
Dell EMC, Cisco, and HPE are all gunning for the throne.
Internet access is often a challenge associated with developing countries. But while many of us in North America have the privilege of access at our fingertips, it’s still a huge barrier to success for many rural and remote Indigenous communities in Canada and the United States.
According to the 2016 Broadband Progress Report, 10% of Americans lack access to broadband. The contrast is even more striking when you look at Internet access in rural areas, with 39% lacking access to broadband of 25/4Mbps, compared to 4% in urban areas.
Many Canadian rural and remote communities face similar access issues. In December 2016, the Canadian Radio-television and Telecommunications Commission (CRTC) set targets for Internet service providers (ISPs) to offer customers in all parts of the country broadband at 50/10Mbps with the option of unlimited data. CRTC estimates two million households, or roughly 18% of Canadians, don’t have access to those speeds or data.
Let those figures sink in for a minute. Today in 2017, millions of people in North America still don’t have access to broadband Internet.
It’s an even harder to pill to swallow when you realize how disproportionately and gravely it affects indigenous communities, many of which are Continue reading
