Dear Tor friends,
the NGO I am volunteering for (Digitalcourage e.V.) has been running modest Tor exits for many years. Now we finally have the opportunity to run a high-bandwidth exit relay because we found a data center with a nice internet connection (20 Gbit/s) we may use.
My question is: What kind of hardware should we buy to utilize this bandwith? I am told that we need an SFP+ networking card to connect to the fibre optics cable, but what CPU and mainboard would you recommend nowadays? It should fit into a 1 height unit 19" enclosure.
If you prefer to tell me in person: I will attend the Tor meetup in Brussels on Friday https://blog.torproject.org/events/tor-meetup-brussels and the subsequent Freedom Not Fear event https://www.freedomnotfear.org/.
Cheers, Christian
Hello Christian, please also report back with the information you found out. I am also pretty interested, running Tor Exits for various German NGOs this really is a topic I am interested in.
Currently the fastests Exit I operate in Germany is "only" doing a little more than 30MiB/s I think. But it only has 1GBit/s connection and I never bothered about this, as I fear the hoster will terminate the contract if I use all bandwidth.
I guess I would
So however, let us know what you found out.
And make sure, if possible, to come to 36c3 meetup. Thanks yl
Hi Christian,
a AMD EPYC 7642 should be able to saturate that 20 GBit/s connection fine, Mainboard depends on what you prefer. Supermicro, HP and so on have all Mainboards for that CPU, so choose the one you prefer.

Dear Tor friends,
Digitalcourage has launched a cluster of new relays on Sunday, and we just turned them into exit relays. We hope they will be pretty fast. They are running on new server metal with a nice connection to the Internet. Nicknames and their fingerprints are as follows:
Digitalcourage4ip1a – Fingerprint 97F51AF6791AD33981CE25DC7A2618429F25B3B0 Digitalcourage4ip1b – Fingerprint BB034C34ED9E60F7709ED93FB432A9BA12A2F2B6 Digitalcourage4ip2a – Fingerprint 68EC657DC8A587B38D5D7763D5C72E93C2CD456C Digitalcourage4ip2b – Fingerprint BA9D7FB9AB4ED0FBCA56941DA22CF7770BA1A4BC Digitalcourage4ip3a – Fingerprint A2DD0EF31813E9B7F6DB435504A406E1AD2B76AB Digitalcourage4ip3b – Fingerprint 35B503FB546815CC9EDE91022555B5D0ED04E389 Digitalcourage4ip4a – Fingerprint FDCFEA18CC64461455DE5EA3FC31834C6B42FEC7 Digitalcourage4ip4b – Fingerprint 8287DADC415B3E667C617EEFB6E7D654C7AC0C47 Digitalcourage4ip5a – Fingerprint 9AD90317DDA2F898EB0AE0F20976EA97E7AF9012 Digitalcourage4ip5b – Fingerprint 902A13399F14FFC7E2912463300C78A25C1F76B6 Digitalcourage4ip6a – Fingerprint 6B61EFE3AEDEB3351FD3C910443D95556316E01C Digitalcourage4ip6b – Fingerprint 762213D327B0A76057F4B61CD587ED4238CD900E Digitalcourage4ip7a – Fingerprint 22296CB6AE56609A96F02FB843AB7B4B0A31CAF4 Digitalcourage4ip7b – Fingerprint D13692D97236C0B8E8E19EA2DD952B5C4F9010BB Digitalcourage4ip8a – Fingerprint 844DC3890E4D04473D10EE65547491F200A86F89 Digitalcourage4ip8b – Fingerprint E2AE93904308E8EB4F8CAE3784D9424B78A4A596

Heartfelt thanks to everyone who helped us with advice, IP addresses, connectivity, Tor, ansible-relayor, GNU/Linux, donations or membership fees!
We will retire our old (generation 3) exit relays by the end of this year. They served as fallback directory mirrors. I will soon write to gus to tell him which new fingerprints could replace them.
Cheers, Christian
