Academics make jump to lightspeed internet

Data and computing initiatives are joining forces to forge a high-speed research network for South Africa.

In bandwidth-thirsty South Africa, the country’s universities and research institutions are oases of the stuff, with a torrent of capacity, up to 10 gigabits a second, running between them. With this internal capacity and international linkages, South African researchers can take part in global projects, such as international astronomy initiatives and the European Organisation for Nuclear Research’s computing grid.

This is because of university and government initiatives set in place a decade ago, and in some instances even longer. For some context, it would take about three seconds to download a full season of Game of Thrones on this research network.

“There’s this big hubbub about big data,” says Professor Colin Wright, special adviser to the Department of Science and Technology on cyber infrastructure. “I think we should just be worried about data. Data is a big issue, especially in the research world. I know that’s also true for the commercial world, but our role is to support research.”

These initiatives – the Centre for High Performance Computing the South African National Research Network (Sanren) Tenet, a private not-for-profit company owned by public research institutions; and the Data Intensive Research Infrastructure for South Africa – are about to be pulled into a single national integrated cyberinfrastructure system, with a dedicated budget.

It is estimated that there are about one million users on this network. For consumers who are lucky to achieve four megabits a second, 10 gigabits a second seems too much for any of us to hope for.

SciBraai, a proudly South African NPO dedicated to science journalism, communication and outreach. SciBraai began on Heritage Day 2013 - Anina Mumm and Engela Duvenage in 2013 launched the website,, to feature stories about South African research, technology and innovation, and the people behind the discoveries. This blog welcomes all South Africans to go behind the scenes of local science and exploration endeavors. It’s a place to share stories about the scientists themselves and the interesting, little-known activities that are often left out of research journals. A place to learn more about the stuff that makes South African science and its people tick. A place to feel inspired about what South Africans are discovering on home soil and abroad. Because local is lekker, no matter what language you use. SciBraai's following has grown in the past years, and we are now on Facebook, Twitter and Instagram. We've also begun organising real-life braai's where we share round-the-fire stories about South African science and scientists.
