A Taxonomy of Internet Shutdowns: The Technologies Behind Network Interference

The paper outlines the various technical mechanisms for implementing a shutdown and the options for mitigating each type. The aim is that technologists and civil society groups working to end shutdowns will find it a valuable technical resource to understand, prepare for, circumvent, and help document deliberate network disruptions.

It is intended to deepen the knowledge of technologists and digital helpdesk practitioners seeking to understand how shutdowns work and mitigate their impact. A glossary is available at the end of the document for a brief explanation of acronyms and technical terms used throughout.
