Tor network latency measurements

June 11, 2021 at 8:00 AM

Network Experiments

What changed?

We are running wide-scale measurements of latencies between relays on the Tor network for an estimated 1-2 months (using many short-lived circuits which will carry a very small amount of traffic).

More details and updates available online and on the tor-relays@ email list.

When did it start?

Around 2021-06-10 16:00:00 UTC.

When did it stop?

Around 2021-12-14 00:00:00 UTC.

What potential problems to look for, and how to report them?

Relays may notice an elevated number of short-lived circuits created and destroyed (we will spread this load over a few hours/days for any individual relay). Be alert for an abnormal number of circuits causing availability issues.

If you think something has gone wrong with the experiment, please contact the experiment team: shortor AT csail.mit.edu or write a follow-up to the tor-relays@ announcement mail mentioned above.
