Hello!
You might recall we ran two "speed tests" so far for investigating the accuracy of a relay's advertised bandwidth, one in 2021[1] and another one earlier this year[2].
We gonna pick this test up again this week. However, this time it won't be just a single run but we are rather scheduling the experiment to be on for two weeks and then off for two weeks for the upcoming weeks/months (see: the third item in our network experiments strategy[3] for some rationale). More exactly: we'll run our measurement script for roughly one week, then wait about a week for flooded values leaving the relay descriptors, then 2 weeks off, then starting again...
The experiment itself has not changed: we are planning to download several large data streams for a period of about 20 seconds with the goal to get a better estimation of the relay's true capacity. There are more details related to this experiment in particular in an older mailing list thread[1], in case anyone is interested and has not seen those yet.
As in previous instances of this "speed test" there is the option for an opt-out. Let us know if any of you doesn't want to participate and we remove your relay(s) from the list to scan.
Finally, an up-to-date status about the flooding being on/off (and other experiments scheduled) can be found on our status page[4].
Thanks, Georg
