Why We Need This New Tool to Measure Internet Resilience

By Guest Writer on June 22, 2022

internet resilience index

The COVID-19 pandemic has made clear that the Internet plays a critical role in society, and it’s underlined the importance of reliable Internet connectivity for everyone. It’s also highlighted a stark reality. Not all countries are on a level playing field with a resilient Internet infrastructure—one that maintains an acceptable level of service in the face of faults and challenges.

Many low-income countries usually have under-provisioned networks and cable infrastructure, or they lack redundant interconnection systems. In these countries (or regions), the likelihood of Internet outages occurring is much higher than in other countries. To help support the development of policies and infrastructure to improve Internet resilience at the local, regional, and global level, we’ve launched a new section on our Internet measurement platform, Pulse, to track resiliency metrics.

What We’re Measuring

  • Infrastructure: The existence and availability of the physical infrastructure that provides Internet connectivity
  • Performance: The ability of the network to provide end users with seamless and reliable access to Internet services
  • Security: The ability of the network to resist intentional or unintentional disruptions through the adoption of security technologies and best practices
  • Market Readiness: The ability of the market to self-regulate and provide affordable prices to end users by maintaining a diverse and competitive market

How We’re Measuring Resilience

The new Internet Resilience focus area is based on the framework outlined in the Measuring Internet Resilience in Africa (MIRA) project overview, a joint initiative of the Internet Society and AFRINIC, the Regional Internet Registry for Africa. One of the main objectives of the MIRA project is to be able to measure, as accurately as possible, the robustness of the Internet ecosystem in a country.

This is not an easy task. There are several building blocks that underpin this complex ecosystem. Additionally, the Internet landscape differs from country to country. To be able to objectively compare countries to one another, we need an objective set of metrics that we can use as a common ground.

To grasp the multi-faceted nature of the Internet we’ve built an index that gives an estimate of the overall Internet resilience of a country. This estimate, or score, is called the Internet Society Internet Resilience Index.

The Internet Society Resilience Index (IRI)

The IRI is built around the four measurement pillars outlined above: Infrastructure, Performance, Security, and Market Readiness.

Each of these four pillars represents core aspects of the Internet. Without them, the Internet wouldn’t be able to operate. The pillars themselves are made up of a series of indicators that provide empirical information about the state of the Internet at country level.

Pillars Dimensions Indicators
Infrastructure Cable ecosystem

Enabling infrastructure
Exit points per 1M
10km fiber reach

Market Readiness Market structure

Data Sources and Weighting

The data from the indicators are collected from various sources, including the World Bank, the International Telecommunication Union (ITU), Packet Clearing House (PCH), Mozilla, the Internet Society, Spamhaus, and the Asia Pacific Network Information Centre (APNIC). We use a weighted sum formula to calculate the final index. You can find more information about the weighting scheme, data sources, rescaling, normalization, and more in the IRI Methodology document.

What’s Next?

The initial focal point of the focus area is on tracking Internet resilience in Africa. We want to test and fine tune the IRI methodology before rolling it out for other regions. No model is perfect, and we are looking at improving on it by collecting additional information and datasets over the coming months. Going forward, we’ll incorporate datasets from the Internet Shutdowns focus area, and from Keeping Traffic Local and Centralization, two new Pulse focus areas that are under development.

  1. The Focus on internet resilience in Africa is great news and the part about reliability is of great importance. The African internet landscape has a huge underserved potential market but with the price discrepancies and equipment costing being shipped in, it removes some part of the middle class and all of the lower class from being part of this, whereas they make up over 85% of the population in these areas.

    We started a company called Octofi Nigeria in West Africa without knowledge of a potential pandemic late 2019 and are focused on bringing about over 50% internet availability and reliability to these regions. We have worked on raising capital from Nigeria and in Africa but it seems instead of the focus to be on expanding the available market, investors focused more on milking the available market in the Fintech space.

    We are currently open to funding and talks to enhance our standing and reach. We have novel methods using large distribution and the African sachetization method to internet provision to help increase availability before focusing on resilience.
