Servers

Country and ISP diversity are approximated by resolving IP addresses to a country code and an autonomous system. We process the capabilities and properties relays and bridges reported to directory authorities.

Network bubble graphs

This image illustrates the uptime of all known relays in a given month. Each row of pixels denotes one consensus (that is, one hour), and each column denotes one relay. Each pixel denotes if a given relay was online or offline at a given hour: black means online, white means offline, and red highlights relays with identical uptime patterns. The complete image gallery can be found on Philipp Winter's homepage.
