Augur is a system that utilizes TCP/IP side channels to measure reachability between two Internet locations without directly controlling a measurement vantage point at either location. It is a scalable, statistically robust methods to infer network-layer filtering, and capable of performing continuous monitoring of global Internet disruption. It is currently deployed and runs Internet-wide disruption tests in nearly 180 countries against sites known to be frequently blocked.

Satellite measures global trends in website deployment and accessibility via the consistency of DNS records. Satellite watches DNS resolution through active measurements of DNS resolvers across the IPv4 address space. A data-set of the alexa top 10,000 domains is collected each week. Satellite is committed to openness, with all code and data made publicly available.

Quack is a technique for detecting content-level disruption. Quack sacrifices idenitification of tightly controlled DPI behavior in exchange for broad measurements of keywords and protocol disruption.

Many sites practice geoblocking due to legal requirements or other business reasons, but excessive blocking can needlessly deny valuable content and services to entire national populations. To help researchers and policymakers understand this phenomenon, we develop a semi-automated system to detect instances where whole websites were rendered inaccessible due to geoblocking.
