Did an earthquake take out SA Internet?

Seabed avalanches caused by an earthquake could have cut several undersea cables, leading to one of South Africa’s biggest Internet outages yet, writes ARTHUR GOLDSTUCK.

There is still no official explanation for freak breaks 11 days ago in two separate undersea cables that provide international access to South Africa’s Internet users. However, as reported in the Sunday Times yesterday, the most common causes of such breaks are damage by ship anchors and earthquakes at sea.

However, the freak occurrence of two separate cables being cut simultaneously far out at sea, as happened on the morning of 16 January, can only be explained by sea-bed activity.  One of the cables was cut in two places, and it is widely believed that a third major cable was also cut.

The cable damage mostly occurred in or near an area called the Congo Canyon, which starts inland and extends 220km into the sea. It is known for having the world’s strongest “turbidity currents”, underwater sediment avalanches over hundreds of kilometers, which are known to destroy undersea cables.

The most likely culprit is a 5.6 magnitude earthquake that struck the Atlantic Ocean near Ascension Island shortly before the cables were cut on the morning of 16 January. The earthquake occurred just before 8am South African time, and local ISPs reported losing international access from just before 10am. The epicentre of the earthquake was more than a thousand kilometres off the coast of Africa, but disturbances caused by seismic activity at sea become more powerful as they approach the coast. Combined with turbidity currents, this could well have taken out all cables in the area.

The West Africa Cable System (WACS) was cut in two places, and the South Atlantic 3 (SAT3) cable in one location. Industry insiders believe that the Africa Coast to Europe (ACE) cable was also cut, but it has not been publicly confirmed.

South Africa is connected to the global Internet via seven such cables, with a total capacity of 42.3 terabits per second (tbps).  These cables, in turn, connect to additional cables connecting the West and East coasts of Africa, with a single cable running from Angola to Brazil providing another 40 tbps.

However, it emerged in the past week that smaller ISPs in South Africa had bought capacity on only one or two cables. In a freak occurrence, two of the most commonly used cables, the WACS and SAT 3 cables, were cut simultaneously, plunging millions of Internet users into data darkness.

Customers of the major mobile network operators – Vodacom and MTN – were largely unaffected, as these tend to have both part-ownership and access to most of the cables running up both the East and West coasts of Africa.

Alexa can now read all messages

For the first time, an Alexa skill is available that makes it possible to listen to any kind of message while driving

Published

For the first time, Alexa users can now hear all their messages and email read aloud.

Amazon’s Alexa has become a household name. The world’s most popular virtual assistant is getting smarter every day and now, with Amazon Echo Auto, it’s in cars too. 

“In today’s highly connected world, messaging in the form of emails, texts, Facebook Messenger, WhatsApp and work channels like Slack, are integral to our daily routine,” says Barrie Arnold, chief revenue officer at ping. “However, distracted driving is responsible for more than 25% of car crashes and thousands of preventable fatalities every year.” 

ping, a specialist in voice technology founded by Arnold and South African Garin Toren, has developed a new Alexa skill as a companion to its patented smartphone app, that enables any message type to be read aloud. Designed for safety, productivity and convenience, “pingloud” is the first skill of its kind for keeping users connected when they need a hand or an extra pair of eyes.

“The ping Alexa skill is specifically designed to help drivers stay off their phones while giving them exactly what they want – access to their messages.” says Toren, ping CEO. 

Opening up Alexa to developers has resulted in an explosion of new skills available either for free or for a fee that unlocks premium services or features. These tools magnify the usefulness of Alexa devices beyond common tasks like asking for the weather, playing music or requesting help on a homework assignment. According to App Annie, the most downloaded apps in 2019 were Facebook Messenger, Facebook’s main app and WhatsApp, highlighting the importance of messaging. 

“The ping Android app is available worldwide from the Google Pay Store, reading all messages out loud in 30 languages,” says Toren. “The iOS version is in global beta testing with the US launch coming very soon.” 

Once you’ve signed up for ping, it takes a few seconds to link with Alexa, enabling all messages and emails to be read aloud by a smart speaker or Echo Auto device. Simply say, “Hey Alexa, open pingloud.” ping links an account to a voice profile so unauthorised users with access to the same Alexa cannot ask for the authorised user’s messages.

All major message types are supported, including Texts/SMS, WhatsApp, Facebook Messenger, WeChat, Snapchat, Slack, Telegram, Twitter DM’s, Instagram, and all email types. Promotional and social emails are not read by default.

Coronavirus to hit 5G

Published

on

Global 5G smartphone shipments are expected to reach 199 million units in 2020, after disruption caused by the coronavirus scare put a cap on sales forecasts, according to the latest research from Strategy Analytics.

Ken Hyers, Director at Strategy Analytics, said, “Global 5G smartphone shipments will grow more than tenfold from 19 million units in 2019 to 199 million in 2020. The 5G segment will be the fastest-growing part of the worldwide smartphone industry this year. Consumers want faster 5G smartphones to surf richer content, such as video or games. We forecast 5G penetration to rise from 1 percent of all smartphones shipped globally in 2019 to 15 percent of total in 2020.”

Ville-Petteri Ukonaho, Associate Director at Strategy Analytics, added, “China, United States, South Korea, Japan and Germany are by far the largest 5G smartphone markets this year. The big-five countries together will make up 9 in 10 of all 5G smartphones sold worldwide in 2020. However, other important regions, like India and Indonesia, are lagging way behind and will not be offering mass-market 5G for at least another year or two.”

Neil Mawston, Executive Director at Strategy Analytics, added, “The global 5G smartphone industry is growing quickly, but the ongoing coronavirus scare and subsequent economic slowdown will put a cap on overall 5G demand this year. The COVID-19 outbreak is currently restricting smartphone production in Asia, disrupting supply chains, and deterring consumers from visiting retail stores to buy new 5G devices in some parts of China. The first half of 2020 will be much weaker than expected for the 5G industry, but we expect a strong bounce-back in the second half of the year if the coronavirus spread is brought under control.”
