we have more bandwidth than we use and we donate this bandwidth to the tor project. we are fans of the tor project and care about protecting personal privacy and individual expression.
we have 3 nodes running up to 4 processes on each node. each node is capable of pushing out up to ~600 Mbps with 4 processes on it. the nodes run bitrig, a fork of openbsd that several of our developers hack on.
EDIT: i just read the linked article and i see why we are listed - we have our own ASN and run openbgpd from our colo space.
