Welcome to Tor Metrics, the primary place to learn interesting facts about the Tor network, the largest deployed anonymity network to date. If something can be measured safely, you'll find it here.*
*And if you can think of something that is missing here, please let us know.
Relays — How many relays contribute their resources to the network, and how many of them permit exiting to the Internet?
Bridges — How many bridges exist to help censored users to connect to the network?
Clients — How many clients connect to the network every day, where do they come from, and what transports are they using?
Pluggable Transports — How many people use pluggable transports to overcome their heavily censored Internet connection?
Hidden Services — How many relays participate in the distributed directory that hidden services use to announce themselves?
Bandwidth — How much bandwidth do relays advertise, and how much of that is actually consumed?
Performance — How long does it take to download a megabyte of data over Tor, and how about five?
Diversity — How diverse is the network in terms of countries or autonomous systems?
About — How are all these facts obtained in an anonymity network without hurting user privacy?
Design prototype note: This is the home page of Tor Metrics which starts with a short statement what the website is about. This page also contains currently eight main categories of Tor network metrics: relays, bridges, clients, pluggable transports, and hidden services can all be seen as network components to some extent; bandwidth, performance, and diversity are different aspects of the network which are mostly unrelated to network components. Metrics will typically be assigned to two or more of these categories, so that they'll be found under more than one of these links. Adding new categories, up to 15 or 20, should be easy and not be limited by the design. The same categories shall also be contained in a navigation bar.
General ideas for this design prototype:
