Canary Watch

This site provides a list of internet companies that explicitly deny having received a legal process that they cannot reveal they have received, and assumes that if this explicit denial is not subsequently made it is because such process is occurring.

Attention: As of May 2016, Canary Watch is no longer being maintained. The Electronic Frontier Foundation, a collaborator for the project, provides an explanation on its blog.
