The Neubot project is based on an open-source computer program, the Neubot, that, downloaded and installed by Internet users, performs quality of service measurements and collects data at a central server. The raw results are published on the web under the terms and conditions of the Creative Commons Zero license. This paper is the guide for researchers and individuals that aims to study, build on and analyze Neubot methodology and results. We provide an exhaustive documentation of Neubot’s HTTP test behavior, along with a discussion of the methodology.
