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.

TikTok takes on COVID-19

The fastest growing social media platform in the world has also become an epicenter of public education about the coronavirus, attracting more than 30-billion views, writes ARTHUR GOLDSTUCK

The young have been getting a bad rap for wanting to party on while COVID-19 sends the world into lockdown. But a different movie is playing itself out on the social platform that is growing fastest among teenagers: TikTok.

Awareness campaigns by TikTok itself, collaboration with the International Red Cross, and spontaneous videos made by TikTok creators have combined into a barrage of information, education, awareness and social consciousness around the coronavirus.

Both globally and in South Africa, TikTok’s COVID-19 campaigns have gone viral.

The local #HayiCorona challenge, designed to remind people not to touch their face and wash hands regularly, has passed 1.5-million views. The TikTok collaboration with the International Red Cross, the #WashingHands challenge, has passed 12.6-million views.

One of the best-known participants in these challenges is the past year’s icon of South African talent, the Ndlovu Youth Choir, took up the global challenge with a 20-second hand-washing video. It put together a performance that brings tremendous energy to what can be a clichéd message, and ends with a punt for the Department of Health’s WhatsApp information service. The video can be viewed below.

“On a global scale, TikTok also partnered with the World Health Organization (WHO) to ensure that, while creators are still having fun and expressing themselves on the platform, they stay informed with COVID-19 information coming from a reliable source,” a TikTok spokesperson told us. “Through the partnership, the WHO has created an informational page on TikTok that offers information to curb the spread of the coronavirus as well as dispelling myths.”

The page can be viewed at https://vm.tiktok.com/GHTEGf

TikTok has hosted a number of livestreams with WHO experts, attracting users from more than 70 countries, tuning in for live question and answer sessions. It has also introduced labels on coronavirus-related videos, to point users to trusted information. Resources are also offered directly in the app and in a dedicated COVID-19 section of TikTok’s Safety Center, at https://www.tiktok.com/safety/resources/covid-19.

If users simply want to explore videos on the topic, they can search via the #coronavirus hashtag, or click on https://vm.tiktok.com/swKbn4. The hashtag has had an astonishing 33.8-billion views, indicating the scale of activity and interest around the topic on the platform.

On World Backup Day: backup, backup, backup

Published

on

It was World Backup Day yesterday, 31 March, at a time when business continuity is threatened as never before. That makes calls for protecting email and defending against ransomware all the more urgent.

The global coronavirus pandemic has brought into stark relief many organisations’ lack of business continuity plans and policies. With more than two billion people around the globe in forced lockdown in wide-ranging government efforts to stem the tide of infections, an unprecedented number of employees are working remotely.

This interruption to the normal way of work is precisely what an effective and resilient business continuity strategy should plan for, says Heino Gevers, cybersecurity specialist at Mimecast

“Companies need uninterrupted access to critical business applications during times of disruption, including safe and secure web and email access for workers that are now operating outside the normal perimeters of the organisation,” he says. “In addition, comprehensive backup and archiving solutions should be ready to restore access to critical business applications should there be any unplanned downtime to ensure continuity until the crisis passes.”

According to Gevers, the current global crisis is likely to push business continuity up the list of priorities for many organisations that have been disrupted by the effects of the coronavirus.

“Organisations are facing new challenges to their productivity; for example in terms of technical support. If a remote user is infected with malware or ransomware, how does the IT team restore that device or do any remediation without being able to physically access it?”

Gevers advises that organisations implement tools that enhances the data protection capabilities of commonly-used tools such as Office365 and can leverage archived data to provide quick recovery of email data in the event of accidental loss, malicious attacks or technical failure. 

“As adoption of cloud-based business applications grow in the wake of forced lockdowns around the globe, companies need to ensure they have the tools to recover in any situation,” he says. “This includes a data management strategy that combines archiving, backup and data protection capabilities to allow for quick restoration of critical systems and applications in the event of disruption.”

Jasmit Sagoo, head of technology at Veritas for the United Kingdom and Ireland, warns that this is a golden age for cybercriminals looking for ransomware opportunities.

“As the global cost of ransomware continues to grow, this World Backup Day, Veritas is saying: ‘don’t pay up, back up!’,” he says. “Ransomware is said to generate an estimated annual revenue of $1 billion a year, and companies who are not consistent in backing up their data are allowing criminals to line their pockets.

“Ransomware attacks exist only because some businesses can’t survive unless the hackers give them back their data.  So, the key to survival is removing that reliance and being able to regain access to data, without engaging with the cybercriminals.  The best way to do that is with a sound backup strategy.

“Sagoo advises organisations to create isolated, offline backup copies of their data to keep it out of reach of any attackers.  They then need to proactively monitor and restrict backup credentials, while running backups frequently to shrink the risk of potential data loss. Businesses should also test and retest their ransomware defences regularly.

“Ransomware strikes without warning and it doesn’t discriminate between its targets – it can happen to any organisation, large or small. Despite their best efforts, most companies will fall to at least one attack. What distinguishes one victim from another is the ability to bounce back, which ultimately depends on its backup strategy.

“When ransomware hits, organisations that aren’t prepared often feel helpless to do anything other than to submit to their attacker’s demands.   That’s why we’re urging all businesses to use World Backup Day as a catalyst to get ahead of the situation and get their data protected.”
