Tor relays

Transparency Report January 2024
In January we kept on making preparations to increase the Nothing to hide organization’s robustness and resilience in 2024. Also the search for the bottlenecks in Tor we experience continued with the help from some wonderful people from the Tor Project. It looks like this will be a long process so we don’t expect short term results.
The metrics used in this report are rounded extrapolated snapshots of the final day of the month, to not give away too much specific information.
1 Requests & orders
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 monthly 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 | 2 | n/a |
| Business entities | 0 | 1 | 0 |
| Natural persons | 0 | 0 | 0 |

2.2 Tor DNS requests
Query response
3.100 per second
Daily queries
267 million
Monthly queries
8.0 billion
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 resolvers.
| Period | Query rate | Daily queries | Monthly queries |
|---|---|---|---|
| November 2022 | 0 | 0 | 0 |
| December 2022 | 870 | 75.000.000 | 2.300.000.000 |

| January 2024 | 3.100 | 267.000.000 | 8.000.000.000 |
Do note that we don’t log the contents of DNS queries.
2.3 Tor diversity
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.

GNU/Linux is slowly but steadily increasing its exit share again. There seems to be a slight increase in guard relay share for BSD though, which is nice.
2.4 DDoS attacks
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.
