Navigating the Ethics of Internet Measurement: Researchers' Perspectives from a Case Study in the EU

TL;DR

The paper investigates how Internet measurement researchers navigate ethical decisions in everyday practice, based on interviews with 16 researchers from an EU group. Using semi-structured interviews and inductive reflexive thematic analysis, it identifies five core challenges: privacy/consent, unintended harm, transparency/accountability, uncertain ethics boundaries, and hurdles in ethics review; it shows that formal guidelines play a limited role, with decisions driven by mentorship, community norms, and practical lab practices. The study further reveals the invisible labor underpinning responsible Internet measurement and frames ethics as craft knowledge transmitted through mentorship and community norms, not merely codified rules. It discusses implications for shared best practices, distributed ethics review, and improved transparency in reporting, stressing the need to balance privacy with data utility while maintaining scientific progress. Overall, the work highlights the intertwined nature of technical and ethical considerations in Internet measurement and calls for formal recognition and support of the labor and expertise required to uphold responsible research across institutions and venues.

Abstract

Internet measurement research is essential for understanding, improving, and securing Internet infrastructure. However, its methods often involve large-scale data collection and user observation, raising complex ethical questions. While recent research has identified ethical challenges in Internet measurement research and laid out best practices, little is known about how researchers actually make ethical decisions in their research practice. To understand how these practices take shape day-to-day from the perspective of Internet measurement researchers, we interviewed 16 researchers from an Internet measurement research group in the EU. Through thematic analysis, we find that researchers deal with five main ethical challenges: privacy and consent issues, the possibility of unintended harm, balancing transparency with security and accountability, uncertain ethical boundaries, and hurdles in the ethics review process. Researchers address these by lab testing, rate limiting, setting up clear communication channels, and relying heavily on mentors and colleagues for guidance. Researchers express that ethical requirements vary across institutions, jurisdictions and conferences, and ethics review boards often lack the technical knowledge to evaluate Internet measurement research. We also highlight the invisible labor of Internet measurement researchers and describe their ethics practices as craft knowledge, both of which are crucial in upholding responsible research practices in the Internet measurement community.
