Purpose

PingER (Ping End-to-end Reporting) is the name given to the Internet End-to-end Performance Measurement (IEPM) project to monitor end-to-end performance of Internet links. The project now involves hundreds of sites in many countries all over the world and we are actively seeking new partners for this project.

Case Studies

This is the list of the Case Studies developed using PingER monitoring Data. They are sorted by regions and by most recent dates first.

Also see https://www.internetperils.com/perilwatch/index.php for routing changes occurring from major events, and Keep it On  on the 213 Internet shutdowns in 2019. An internet shutdown happens when someone — usually a government — intentionally disrupts the internet or mobile apps to control what people say or do.
