Explanation on (negative) spikes in number of relays
by ttlns 16 Apr '26

16 Apr '26

Around 2 weeks ago, I posted the following concerns regarding "negative spikes" for the number of relays measured by metrics.torproject.org [1] in forum.torproject.org [2] (and earlier on r/TOR [3] ) : > Are there any good explanations on why these spikes occurred? > Might those outages imply some centralized infrastructure? If so, how is that not a major concern? So far, I have not received any definite explanations. If those spikes happen to be measurement errors, I imagine that there should be logs somewhere to support this explanation. 3. Does such evidence exist publicly? 4. If not (3), where would that evidence be stored? Sources: [1] http://metrics.torproject.org/networksize.html?start=2022-01-01&end=2026-03… [2] https://forum.torproject.org/t/explanation-on-negative-spikes-in-number-of-… [3] https://www.reddit.com/r/TOR/comments/1s8wx24/explanation_on_spikes_in_numb… I appreciate any clues, hints, or pointers on where to ask further. Best, ttlns

incorrect data on metrics.torproject.org relay search

Please explain how a Tor relay can have graphs on https://metrics.torproject.org/rs.html#details/506C582367B6ABED6EEF3936DCEB… since 2023-02-17 but at the same time have "First Seen 2026-04-06 23:00:00 (7 days 9 hours 22 minutes and 50 seconds)" in the data. Why has the "first seen" of my 3 year old relay reset? regards txt.file PS: Am not subscribed to this list.
