Tor relays

This is the first quarterly report because we changed from monthly reports to quarterly reports after March 2024.
In the second quarter (Q2) of 2024 we advanced our efforts to increase the Nothing to hide organization’s robustness and resilience. We now have our own autonomous system and IP addresses so our infrastructure is more independant. In Q3 and Q4 we plan to take the new autonomous system with dedicated networking equipment in to production. We also added servers to two new datacenters for additional DNS and Tor infrastructure.
Also the search for the bottlenecks in Tor we experience continued with the help from some wonderful people from the Tor Project. We made some progress by ruling out some possible causes for the bottlenecks and also learned that some assumptions about the Tor network aren’t true (anymore). For now we increased our bandwidth quite a bit by converting some underutilized exit relays to guard relays and we keep on experimenting and researching the performance problems we have with Tor.
Our project where we work on better DNS mitigation for correlation attacks and timeless timing attacks has had a few significant delays. We try to involve as much relevant and smart people as possible, but in turn this also slows things down. We hope to give a bigger update with more content and specifics in Q3 or Q4 at the latest.
The metrics used in this report are rounded extrapolated snapshots of the final day of the quarter, to not give away too much specific information.
As a provider of pass-through anonimity services, Nothing to hide receives messages about network traffic originating from or destined for our networks on a daily basis. While the vast majority of these messages are general notices send by automated systems, some of them contain legitimate complaints, requests and/or (court) orders/subpoenas directed at Nothing to hide.
Below we report on the quarterly amount of these messages we get from judicial authorities (courts, judges, juries), law enforcement agencies (LEA), business entities and natural persons.
Sender | Complaints | Requests | Orders/subpoenas |
---|---|---|---|
Judicial authorities | n/a | 0 | 0 |
Law enforcement agencies | n/a | 7 | 0 |
Business entities | 1 | 6 | 0 |
Natural persons | 0 | 0 | 0 |

DNS requests on the Tor network are resolved by the Tor exit relays. This means that high capacity Tor exit relays can generate a lot of DNS queries. These queries are being resolved by multiple high capacity DNS recursors.

Do note that we don’t log the contents of DNS queries.
One of our major goals is to break the GNU/Linux monoculture currently present on the Tor network. Monocultures in nature are dangerous, as vulnerabilities are held in common across a broad spectrum. In a globally used anonymity network, monocultures can be disastrous.
We make the Tor network stronger and more resilient by running all our relays on FreeBSD. Here we report on our ongoing effort to increase operating system diversity on the Tor network. If any Tor operator reading this is interested in running Tor relays on BSD, please contact us and we will gladly help out.

We converted some exit relays to be guard relays and while this increased our overall bandwidth and more than tripled the guard relay share of non-GNU/Linux operating systems, the exit relay share decreased considerably as a result.
Aside from the occasional (big) DDoS attack, it’s relatively quiet in terms of DDoS attacks. The Russian government must be busy with something else.
