The Transformations Shaping 2019
We don’t need new technologies in 2019, what we need is a complete vision for applying those new technologies. That’s a vision that our transformations will provide, at long last. In fact, in 2019, they’ll usher in the new age of computing.
Emerging Technologies: Bridging the Digital Gap in Africa
With all the excitement about the role of technology in contributing to social change and improved development outcomes across Africa, it is easy to forget that only 11% of the world’s Internet subscribers are Africans, while only 35.2% of Africans use the Internet. An effective science and innovation system in any country, and globally, I believe, depends on strong basic research and higher education infrastructure. In addition to knowledge production, basic research facilities, development of human resources, and applications are critical. But in the course of conducting, applying, and managing research, both researchers and managers of research and innovation have information needs. These needs must be satisfied in order for the scientists and the science innovation system to function effectively.
My recent participation at the 13th Internet Governance Forum (IGF) in Paris as a Youth@IGF Fellows brought me closer to the realization that technology has really increased the speed and reach of information everywhere – and now to communities in Africa.
Africa is leapfrogging information and communication technology development, which is also fueled by mobile broadband, but there are also worrying trends, such as a growing the digital divide between men and women, and between urban and rural areas.

Zimbabwe Chapter Meetup on IoT: Converse / Create / Collaborate
On December 6th 2018, the Internet Society Zimbabwe Chapter held an Internet of Things (IoT) meetup supported by the Beyond the Net Small Grants, a programme intented to assist the Internet Society Chapters with financial support to organize initiatives that contribute to the development of their communities.
An exciting convening brought together Zimbabweans with a keen interest in solving some of the pressing issues facing the country using IoT. The meetup was a drive by the Zimbabwe Chapter to create a platform for conversations around IoT security and the potential benefits of Internet-connected devices. More so, it sought to harness innovation potential by creating a space for IoT creativity and collaboration. It ran under the tagline “Converse/Create/Collaborate.”
The meetup was engineered on the basis that in order to push the IoT Security agenda forward there is need to use a multistakeholder approach. The first section of the meetup was a conversation on the subject matter through a keynote presentation and a panel discussion. Solomon Kembo gave the keynote talk and really set the pace on what IoT was and how it would solve most of our challenges in society. He also talked about the IoT projects that the Continue reading

Cisco Champion for 2019
Again I made it to the list of Cisco Champions, making this the second year in a row! I am so glad that my effort to give back to the community and to all my networking fellows out there paid off again in the shape of this recognition from Cisco. This badge is only a small thing, relating to all the community connections and sharing that my involvement with networking community via social media and this blog, made possible. It only pushes me to get even more done in the future. In 2018 I was involved in a few very challenging new

Un triste début d’année pour le Congo
À peine la page du calendrier tournée que nous constatons plus de troubles sur Internet.
Aujourd’hui, Cloudflare peut confirmer, chiffres à l’appui, qu’Internet a été coupé en République Démocratique du Congo, information précédemment révélée par de multiples organes de presse. Cette coupure a eu lieu alors que se déroulait l’élection présidentielle le 30 Décembre dernier, et perdure pendant la publication des résultats.
Tristement, cette situation est loin d’être une nouveauté. Nous avons fait état d'événements similaires par le passé, y compris lors d’une autre coupure d’Internet en RDC il y a moins d’un an. Une courbe malheureusement bien familière est aujourd’hui visible sur notre plateforme de gestion du réseau, montrant que le trafic dans le pays atteint péniblement un quart de son niveau habituel.
Notez que le diagramme est gradué en temps UTC, et que la capitale de la RDC Kinshasa est dans le fuseau horaire GMT+1.
La chute du trafic a démarré en milieu de journée le 31 Décembre 2018 (à environ 10h30 UTC, soit 11h30 heure locale à Kinshasa). Celà est d’autant plus frappant quand sont superposées toutes les courbes quotidiennes:
Ci-dessus, la courbe rouge représente le trafic du 31 Décembre, et les courbes grises celui des 8 Continue reading
Sad start to the new year in the Democratic Republic of the Congo
The calendar has barely flipped to 2019 and already we’re seeing Internet disruptions.
Today, Cloudflare can quantitatively confirm that Internet access has been shut down in the Democratic Republic of the Congo, information already reported by many press organisations. This shutdown occurred as the presidential election was taking place on December the 30th, and continues as the results are published.
Sadly, this act is far from unprecedented. We have published many posts about events like this in the past, including a different post about roughly three days of Internet disruption in the Democratic Republic of the Congo less than a year ago. A painfully familiar shape can be seen on our network monitoring platform, showing that the traffic in the country is barely reaching a quarter of its typical level:
Note that the graph is based on UTC and Democratic Republic of the Congo’s capital Kinshasa has the timezone of GMT+1.
The drop in bandwidth started just before midday on 31 December 2018 (around 10:30 UTC, 11:30 local time in Kinshasa). This can be clearly seen if we overlay each 24 hour day over each other:
The red line is 31 December, the gray lines the previous eight days. Looking Continue reading

Whither Network Engineering? (Part 1)
An article on successful writers who end up driving delivery trucks. My current reading in epistemology for an upcoming PhD seminar. An article on the bifurcation of network engineering skills. Several conversations on various slacks I participate in. What do these things have in common? Just this:
What is to become of network engineering?
While it seems obvious network engineering is changing, it is not so easy to say how it is changing, and how network engineers can survive those changes. To better understand these things, it is good to back up and take in a larger view. A good place to start is to think about how networks are built today.
Networks today are built using an appliance and circuit model. To build a network, an “engineer” (we can argue over the meaning of that word) tries to gauge how much traffic needs to be moved between different points in the business’ geographical space, and then tries to understand the shape of that traffic. Is it layer 2, or layer 3? Which application needs priority over some other application?
Once this set of requirements is drawn up, a long discussion over the right appliances and circuits to purchase to Continue reading
