NAPAfrica enters IXP top 15

Teraco, Africa’s only vendor neutral data centre, has announced that Africa’s largest Internet Exchange Point (IXP), NAPAfrica is now ranked in the top 15 of the largest global IXPs.

This ranking position is in terms of the number of unique ASNs or peering members across the IXP. Andrew Owens, Technical Manager – Interconnection & Peering, Teraco, says that NAPAfrica has 323 members and has truly established itself as the interconnection and content hub for sub-Saharan Africa, connecting to over 350 unique ASN’s servicing 16 countries.

Owens says that the success of an IXP should be measured by its ability to sustainably contribute to the development of the Internet ecosystem within its community: “Several NAPAfrica members claim that as much as 80% of their traffic is peered at the exchange. This significantly lowers transport costs across the southern continent and enables clients to offer a better service at far more competitive prices.”

In 2010, Teraco approached the Internet Service Provider’s Association (ISPA) to suggest moving the Johannesburg Internet Exchange (JINX) and establish the Cape Town Internet Exchange (CINX) at Teraco’s facilities, which was the only neutral data centre available at the time. The proposal was rejected, which led to Lex van Wyk and Andrew Owens building an exchange. This was the start of a great Internet adventure and a steep learning curve for Teraco.

The first significant milestone was reached when Google joined the IXP and started peering its content in 2012. “Later that same year more content providers joined, most notably Akamai and Optinet, and the exchange soared to a new high of 1Gbps of traffic. Members soon realised the very real value of picking up content locally,” says Owens.  He says that the exchange has also become more attractive as content players watch the number of users and traffic increase.

By 2016, NAPAfrica exceeded peak daily throughput of 100Gbps; Telkom Openserve announced its decision to peer and the NAPAfrica community was firmly on the map as the largest in Africa. Early 2017 saw NAPAfrica upgrading its infrastructure to a new Arista platform. Owens says this was driven by client demand as they continued to enjoy the growth in Internet traffic across the continent: “100Gbps ports are the new standard and we are upgrading existing clients on a daily basis,” says Owens.

He says that the first client to upgrade to a 100Gbps port was Afrihost and the demand has continued: “The NAPAfrica platform has the hardware, capability and traffic to support this level of investment into Internet infrastructure. Prices have also dropped significantly, down to around 25% of the levels last seen in late 2016, making this an affordable option when upgrading.”

As Southern Africa continues to grow and prove itself to be the African continent’s largest colocation market, larger than the next 20 African markets combined according to Xalam Analytics, the role of an IXP such as NAPAfrica becomes more critical. “Developing Africa’s Internet ecosystem is a primary role of an IXP together with infrastructure providers such as Teraco. In the eight years since the start of NAPAfrica, sub-Saharan Africa has benefited from local and international content from leading providers such as Akamai, Cloudflare, Facebook, Google, Netflix, Microsoft, Amazon, Verizon Digital Media, Limelight and Optinet.” 

Because most of the major network operators in Southern Africa peer at NAPAfrica, large amounts of content reach the man on the street.  This combination of network and content operators working together, assists in making the end user Internet work.

Achieving a position in the top 15 globally, Owens says; “NAPAfrica will continue to upgrade its infrastructure. The volume of Internet traffic is steadily increasing with Johannesburg reaching 400Gbps, and Cape Town is almost at 100Gbps. We are ready to meet further demand and growth.”

Kenya tool to help companies prepare for emergencies

After its team members survived last week’s Nairobi terror attack, Ushahidi decided to release a new preparedness tool for free, writes its CEO, NAT MANNING

Published

On Tuesday I woke up a bit before 7am in Berkeley, California where I live. I made some coffee and went over to my computer to start my work day. I checked my Slack and the news and quickly found out that there was an ongoing terrorist attack at 14 Riverside Complex in Nairobi, Kenya. The Ushahidi office is in Nairobi and about a third of our team is based there (the rest of us are spread across 10 other countries).

As I read the news, my heart plummeted, and I immediately asked the question, “is everyone on my team okay?”

Five years ago Al-Shabaab committed a similar attack at the Westgate Mall. We spent several tense hours figuring out if any of our team had been in the mall, and verifying that everyone was safe. We found out that one of our team member’s family was caught up in the attack. Luckily they made it out.

At Ushahidi we make software for crisis response, including tools to map disasters and election violence, and yet we felt helpless in the face of this attack. In the days following the Westgate attack, our team huddled and thought about what we could build that would help our team — and other teams — if we found ourselves in a similar situation to this attack again. We identified that when we first learned of the attack, nearly everyone at Ushahidi had spent that first precious few hours trying to answer the basic questions, “Is everyone okay?”, and if not, “Who needs help?” 

People had ad-hoc used multiple channels such as WhatsApp, called, emailed, or texted. We had done this for each person at Ushahidi (their job), in our families, and important people in our community. Our process was unorganised, inefficient, repetitive, and frustrating.

And from this problem we created TenFour, a check in tool that makes it easier for teams to reach one another during times of crisis. It is a simple application that lets people send a message to their team via SMS, Slack, Voice, email, and in-app, and get a response. It also works for educational institutions, companies with distributed staff, as well as part of neighbourhood networks like neighbourhood watches.

This week when I woke up to the news of the attack at Riverside, I immediately opened up the TenFour app.

Kia multi-collision airbags

Published

on

The world’s first multi-collision airbag system has been unveiled by Hyundai Motor Group subsidiary KIA Motors, with the aim of improving airbag performance in multi-collision accidents.

Multi-collision accidents are those in which the primary impact is followed by collisions with secondary objects, such as other vehicles, trees, or electrical posts, which occur in three out of every 10 accidents. Current airbag systems do not offer secondary protection when the initial impact is insufficient to cause them to deploy. 

However, the multi-collision airbag system allows airbags to deploy effectively upon a secondary impact, by calibrating the status of the vehicle and the occupants.

The new technology detects occupants’ positions in the cabin following an initial collision. When occupants are forced into unusual positions, the effectiveness of existing safety technology may be compromised. Multi-collision airbag systems are designed to deploy even faster when initial safety systems may not be effective, providing additional safety when drivers and passengers are most vulnerable. By recalibrating the collision intensity required for deployment, the airbag system responds more promptly during the secondary impact, thereby improving the safety of multi-collision vehicle occupants.

“By improving airbag performance in multi-collision scenarios, we expect to significantly improve the safety of our drivers and passengers,” said Taesoo Chi, head of the Hyundai Motor Group’s Chassis Technology Centre. “We will continue our research on more diverse crash situations as part of our commitment to producing even safer vehicles that protect occupants and prevent injuries.”

According to statistics by the National Automotive Sampling System Crashworthiness Data System (NASS-CDS), an office of the National Highway Traffic Safety Administration (NHTSA) in USA, about 30% of 56,000 vehicle accidents from 2000 to 2012 in the North American region involved multi-collisions. The leading type of multi-collision accidents involved cars crossing over the centre line (30.8%), followed by collisions caused by a sudden stop at highway tollgates (13.5%), highway median strip collisions (8.0%), and sideswiping and collision with trees and electric poles (4.0%). 

These multi-collision scenarios were analysed in multilateral ways to improve airbag performance and precision in secondary collisions. Once commercialised, the system will be implemented in future new KIA vehicles.
