Building a Community LTE Network in Bokondini, Indonesia
As part of our work in the University of Washington’s Information and Communications Technology for Development (ICTD) Lab, we recently spent four weeks in Bokondini, a village in the Papuan Highlands. During our time in Bokondini, we helped some community members extend Internet access throughout the village via a community LTE network, using a technology stack that we call CoLTE (for Community LTE).
The Area and Background
Bokondini is a small village (population ~1,500) in the Baliem Valley, a mountainous region located in the highlands of Indonesian Papua. The Papuan Highlands are a famously rugged, remote, and hard-to-cover area, and many inhabitants of the region live without any form of telecommunications whatsoever. Infrastructure in Bokondini is a remarkably ad-hoc process; for example, electricity comes from a small set of solar panels and a micro hydro generator, and tends to shut off between the hours of 9pm and 6am.
Bokondini’s current relationship to the Internet revolves primarily around the local school. The community pays for a small (1Mbps) satellite Internet connection that terminates at the local elementary school, where it’s used to provide WiFi coverage to teachers on the school campus. Coverage is extended to a few other houses in Continue reading
Introducing Cloudflare Registrar: Domain Registration You Can Love
“I love my domain registrar.” Has anyone ever said this? From before Cloudflare even launched in September 2010, our early beta customers were literally begging us: "Will you please launch a registrar too?!" Today we're doing just that, launching the first registrar we hope you’ll be able to say you love. It's built around three principles: trust, security, and always-fair pricing. And it’s available to all Cloudflare customers.
Needing Secure Domain Registration Ourselves
Cloudflare has actually run a registrar for some time. Like many of our best products, it started by solving an internal issue we had. Cloudflare has several mission-critical domains. If the registration of these domains were ever compromised, it would be, in a word, bad.
For years, we worked with our original domain registrar to ensure these domains were as locked down as possible. Unfortunately, in 2013, a hacker was able to compromise several of the systems of the registrar we used and come perilously close to taking over some of our domains.
That began a process of us looking for a better registrar. Unfortunately, even the registrars that charge hefty premiums and promise to be very secure turn out to have pretty lousy security. Continue reading
Cloudflare Registrar: what happens when you register a domain?
Every website, large or small, started with an idea, rapidly followed by registering a domain. Most registrars offer promotions for your initial domain registration and then quietly hike the price with each renewal. What they don’t tell customers is that the price they pay to a registry, for your registration, is set by the registry. In some cases, we’ve found registrars charging eight times the wholesale price for a domain renewal.
Today, we’re launching Cloudflare Registrar, the first domain registrar you can love. Cloudflare Registrar will never charge you more than what we pay to the registry for your domain. No markup and no surprise fees. For eight years Cloudflare has built products that make the internet faster and safer. It's time for us to start where your internet journey starts, your domain.
A quick introduction to domain registration
When you register a domain, you become the owner, or registrant, for that domain for a set period of time. Now that you are the registrant, you can create an authoritative record that tells the world the nameservers for your domain. The domain name system, or DNS, uses those nameservers to direct traffic to the IP address of your server.
A Markdown-to-PDF Workflow on Linux
In May of last year I wrote about using a Makefile with Markdown documents, in which I described how I use make and a Makefile along with CLI tools like multimarkdown (the binary, not the format) and Pandoc. At that time, I’d figured out how to use combinations of the various CLI tools to create various formats from the source Markdown document. The one format I hadn’t gotten right at that time was PDF. Pandoc can create PDFs, but only if LaTeX is installed. This article describes a method I found that allows me to create PDFs from my Markdown documents without using LaTeX.
Two tools are involved in this new conversion process: Pandoc, which I’ve discussed on this site before; and wkhtmltopdf, a new tool I just recently discovered. Basically, I use Pandoc to go from Markdown (MultiMarkdown, specifically) to HTML, and then use wkhtmltopdf to generate a PDF file from the HTML.
The first step in the process is to use Pandoc to convert from Markdown to HTML, including the use of CSS to include custom formatting. The command looks something like this:
pandoc --from=markdown_mmd+yaml_metadata_block+smart --standalone \
--to=html -V css=/home/slowe/Documents/std-styles.css \
--output=<destination-html-filename> <source-md-filename>
This generates Continue reading

Implications of Valley-Free Routing in Data Center Fabrics
As I explained in a previous blog post, most leaf-and-spine best-practices (as in: what to do if you have no clue) use BGP as the IGP routing protocol (regardless of whether it’s needed) with the same AS number shared across all spine switches to implement valley-free routing.
This design has an interesting consequence: when a link between a leaf and a spine switch fails, they can no longer communicate.
For example, when the link between L1 and C1 in the following diagram fails, there’s no connectivity between L1 and C1 as there’s no valley-free path between them.
