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).
Around 2021-06-10 16:00:00 UTC.
It is still ongoing.
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
shortor AT csail.mit.edu or write a follow-up to the
tor-relays@ announcement mail mentioned above.
