Tor Metrics


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 come across something that is missing here, please let us know.

Servers

How many relays and bridges are in the network? How many of them permit exiting?

Bandwidth

How much bandwidth do relays advertise? And how much of that is actually consumed?

Diversity

How diverse is the network? In which countries are relays located?

Users

Where do users come from? What transports and IP versions are they using?

Performance

How long does it take to download a megabyte of data over Tor? How about five?
