Almost a year later, I now have an update! dotsrc.org is now hosting exit nodes! https://metrics.torproject.org/rs.html#search/dotsrc

We ended up getting our own AS number and IPv6 addresses. IPv4 addresses were harder to come by, but we found someone who could lend us a /24 block.

Thanks to those of you reaching out. Especially this article was helpful: Operating Tor Relays at Universities: Experiences and Considerations https://arxiv.org/abs/2106.04277

Hi All!

At dotsrc.org we are trying to run Tor exits on the Danish NREN, just like 'Digital Society' does in Switzerland https://metrics.torproject.org/rs.html#search/as:AS559, and 'Heart for Internetfreedom' does in the Netherlands https://metrics.torproject.org/rs.html#search/flag:exit%20as:1101.

We have been running two Tor exit nodes for a couple of months, and we've just been asked to shut them down by our ISP DeiC (AS1835) who runs the Danish research network "Forskningsnettet". Their reasoning for banning Tor exits is that other European universities don't expect bad traffic from "Forskningsnettet".

We're currently working with DeiC to find a solution. We would prefer if they could just change the abuse contact for our IP range to tor-abuse@dotsrc.org, but they are pushing for us getting our own AS number.

Anybody with experience running a Tor exit on a NREN? If you have a contact person at a NREN, maybe you could ask why they decided to allow Tor exit traffic. That answer would be helpful in our discussions with DeiC. Are there any other organizations running Tor exits on the European NRENs than the two we mentioned?

Thanks!
