Since July 2017, there has been a steady decline in relays from ~7k to now ~6.5k. This is a bit unusual that is we don't see often such a steady behavior of relays going offline (at least that I can remember...).
It could certainly be something normal here. However, we shouldn't rule out a bug in tor as well. The steadyness of the decline makes me a bit more worried than usual.
That being said, I don't have an easy way to list which relays went offline during the decline (since July basically) to see if a common pattern emerges.
So few things. First, if anyone on this list noticed that their relay went off the consensus while still having tor running, it is a good time to inform this thread :).
Second, anyone could have an idea of what possibly is going on that is have one or more theories. Even better, if you have some tooling to try to list which relays went offline, that would be _awesome_.
a) Please find two pictures which show tap[1] and ntor[2] in 2016 and 2017 for a certain relay. Obviously the number of tap/ntor increases since July 2017. b) Taps becoming hourly massive on all my guards since October 2017. c) An other relay had the largest amount of taps. It received 6 million taps. The tap flood took 65 minutes and the tor cpu power went up from 60% before to 120-210% during the flood. I can not prove but because of outbound packet abuse letters from an ISP I start thinking if this is an other measure to damage guard/hsdir flags. Beside the enormous consumption of cpu resources. I hope this helps.
