The network

To learn about the network you can look at the graphs about it and fast exits.

To learn about users of the network you can look at graphics about them. They are counted in a privacy preserving way. Bridge users might not be counted accurately enough, but this is subject to change without decreasing anonymity.

There are also graphics about the performance of the network.

The metrics are configurable, however there is an interactive version.

The data behind all these graphs can be found here.

ExoneraTor helps you to find out if a given IP address was a Tor relay and if it was an exit that allowed connections to an IP.

Relay Search lets you search for nickname, $-prefixed fingerprint, or IP address.

The consensus health page was set up to display the status of a recent consensus.

There are still TorStatus websites, but the code behind them is unmaintained and your browser might freeze, because the list of relays is displayed in total and shows many details. However there’s Atlas which lets you search for currently running or recently running relays.

Atlas gives you an overview about the results. The nickname(s) it has found, the bandwidth, uptime, location (country), IP address, flags assigned, ports for connections.

Compass enables you to search for groups of relays. For example all exits in a specific country or set of countries. From this list it is possible to jump to Atlas by clicking on the short fingerprint.
