The reality today is that the Internet is more often used to send exactly the same thing to many people, and it’s doing a huge amount of that now, much of which is in the form of video. But this design is not well suited for the mass consumption of static content, such as movies or TV shows. This approach made sense when the Internet was used mainly to deliver different content to different people. It’s a model that works well for sending unique information from one point to another, say, your bank statement or a letter from a loved one. This scheme assigns addresses to specific devices-people’s computers as well as servers-and uses those addresses to send data between them as needed. Internet Protocol (IP), defines an addressing scheme that computers use to communicate with one another. The core protocol of the Internet, aptly named the To understand the alternative approach we’re championing, though, you first need to recall how the Internet works. But in countries without the same level of investment in network infrastructure, the picture was less rosy: Internet service providers (ISPs) in South Africa and Venezuela, for instance, reported significant strain.īut is overprovisioning the only way to ensure resilience? We don’t think so. That’s because most of their networks were overprovisioned, with more capacity than they usually need. As a precaution, some Internet providers scaled back service levels temporarily, although that probably wasn’t necessary for countries in Asia, Europe, and North America, which were generally able to cope with the surge in demand caused by people teleworking (and binge-watching Netflix). When the COVID-19 pandemic erupted in early 2020, the world made an unprecedented shift to remote work.
