Looking glasses (LG) servers enhance our visibility into Internet connectivity and performance by offering a set of distributed vantage points that allow both data plane and control plane measurements. However, the lack of input and output standardization and limitations in querying frequency have hindered the development of automated measurement tools that would allow systematic use of LGs. In this paper we introduce Periscope, a publicly-accessible overlay that unifies LGs into a single platform and automates the discovery and use of LG capabilities. Periscope can handle large bursts of requests, with an intelligent controller coordinating multiple concurrent user queries without violating the various LG querying rate limitations. I show that Periscope significantly extends our view of Internet topology with over 2,000 vantage points in 478 cities.
