Hi Moritz,
DFRI [1] is running two relays, DFRI0 and DFRI3, which should qualify as fast relays as defined by sponsor j. (They were just recently bumped From 10 MB to 12.5 MB. They both have an exit policy allowing the ports explicitly required on https://trac.torproject.org/projects/tor/wiki/org/sponsors/SponsorJ.)
We'd love to be able to get some funds for this which would make it possible for us to run more exit traffic. We only have one /24 network to run exit traffic from atm though so this is all we can do for now without breaking the stated diversity rules. (Anybody sitting on an IPv4 /24 PI that we can borrow for a year or so? We'd handle it with care!)
We could technically run bridges too but we would have to discuss this internally some more first. Do we really want to take money for running entry _and_ exit relays? Isn't that exactly how you'd attack Tor users if you had the power, by controlling entry and exit? If we've missed some public discussion on this topic, please point us at it.
Thanks, Linus, DFRI
