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.
We've made some significant changes to how we calculate the IRI. See our release note [12 November 2025] for details.

Serbia
57 / 100
The Internet in Serbia is less resilient on average than other countries in Southern Europe, and is low for Europe. It ranks 5th in Southern Europe for security, a category that evaluates the use of technologies and best practices that support a network’s ability to resist disruptions. It ranks 37th in Europe for market readiness, a category that evaluates the overall competitiveness of the market, and the ability to offer affordable prices to consumers.

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 IRI methodology.
Our definition of Internet resilience
A resilient Internet connection is one that can maintain an acceptable level of service in the face of faults and challenges to normal operation. These challenges may include sudden changes in Internet traffic, suspicious activity, unexpected outages, and more.
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.
