A frequently stated problem with Tor is the poor performance and
improving this is the goal of several sub-projects. One of these is to
simply encourage the deployment of more Tor servers. This will
increase the capacity of the network, but the consequent improvement
to users is more difficult to
Some of you might remember my email to this list in February, where I
asked for help from operators of Tor nodes in the UK [1]. This was for
an experiment to establish how diverse the topology of the Tor network
is -- an important component of how secure it is against traffic
analysis. Thanks to

The convention in anonymity research is to assume a global passive

I'm a researcher at the University of Cambridge, and I'm studying
anonymous communication systems (e.g. Tor). I also operate a Tor node
(ephemer) myself.
Currently, I'm working on a study to discover how diverse the location
of Tor nodes is on the Internet, to see how secure it is against
