Internet Resilience Index

For people to experience the full benefits of access, the Internet itself needs to be able to adapt to challenges. The Pulse Internet Resilience Index (IRI) tracks a range of indicators and assigns a weighted score for each country, measured out of 100. It’s a holistic score that measures how well an Internet connection can withstand things like sudden changes in Internet traffic, suspicious activity, or unexpected outages.

About the Internet Resilience Index

The Pulse Internet Resilience Index (IRI) draws from a range of data sources, to track some of the key building blocks that underpin the Internet. The IRI enables comparison between countries, regions, and sub-regions, with a balanced set of metrics that accounts for the Internet’s complex ecosystem and varied landscape.

Each country is assigned an Internet Resilience Score, calculated out of 100. It reflects four broad pillars, each representing a range of different components that contribute to the overall resilience of the Internet. Scores are weighted, so a drop or a rise in one indicator can mean an improvement in this country, or that others are over- or under-performing in that area.

Learn more about how we choose indicators and data sources, and about our weighting scheme and aggregation method in the methodology document [PDF].

Origins of the IRI

The Internet Resilience Index developed out of the Measuring Internet Resilience in Africa (MIRA) project. It uses best practices according to the EU-JRC and the OECD Handbook on Constructing Composite Indicators and the same methodology as currently existing indices such as the GSMA Mobile Connectivity Index, the Facebook/EIU Inclusive Internet Index and the Web Foundation Web Index.
