Australia NBN Data Traffic Up 70%

NBN data traffic is up 70 per cent during the business hours, according to the Australian Competition and Consumer Commission, while mobile call volumes are up 50 percent on some routes. 

But the stay-at-home shift is not “breaking the internet." The sudden adoption of “stay at home” policies in many countries will provide a “stress test” for communications networks at the same time, revealing which networks are resilient, and which are less so. So far, there are few reports of problems, though perhaps it is inevitable that speculation about breaking the internet will prove irresistible storylines. 

The real story is the absence of reports about actual service degradation. A few service providers already have released data on the spike in usage.

Verizon reported that between March 12 and March 19, 2020, total voice usage on Verizon networks was up 25 percent, with the primary driver being use of conference call services.

Cisco reports that traffic on the Webex backbone connecting China-based Webex users to their global workplaces has increased as much as 22 times since the Covid-19 outbreak began. During the same time period, Webex also saw four to five times as many users in Japan, South Korea and Singapore, with the average time spent on Webex video meetings doubling among users in those countries.

Mobile voice usage was up 10 percent, while call duration was up 15 percent. Presumably much of that is related to the use of conference calling services. Still, voice traffic requires so little bandwidth that none of that would affect user experience overall. 

Virtual private network traffic was up 25 percent and web traffic was up 22 percent. 

With so many people now working at home, with schools closed, entertainment video and game play bandwidth consumption are new concerns for internet service and app providers. Some note that it is streaming video that represents the single biggest source of new demand on access networks. 

Streaming Netflix at high-definition settings uses up to 3000 MB per hour. Netflix in 4K will use even more. A virtual Zoom meeting, using 1080p settings consumes 1.8 Mbps, or about 810 MB per hour. 

Fortnite and Minecraft both reportedly use about 100 megabytes of data per hour, according to Chris Hoffman, How-To Geek editor. Most games likely consume 40 MB to 150 MB per hour. 

Perhaps some are surprised that global networks are holding up so well under the sudden additional load. That is testament to the investments internet service providers, cloud data centers and capacity suppliers have made over the past couple of decades.
