Re: [tor-relays] Decline in relays



(don't take this information as granted this was a quick 'n dirty thing)

David Goulet:
> Since July 2017

It appears to have started earlier than July if you graph metrics' csv
file for better granularity. Maybe somewhere in mid May 2017 (maybe when
tor 0.2.9.x -> 0.3.0 started to spread? -> correlate it with the relays
by version graph)

> which relays went offline

I compared two sets of relays (identified by FP):

1) all relays included in onionoo data from 2017-05-07 00:00
(that means also non-running relays that were running at some point
during the week before that timestamp)
This set has 7334 _running_ relays (8681 in total)

2) all relays - including non-running relays - included in onionoo data
from 2017-10-23 21:00 that were added to the tor network **before**
2017-05-07.
This set contains 5151 relays in total.

I'm afraid the results are not very useful due to the apparently high
churn rate. 3885 relays that were in (1) are NOT in (2).


Disappeared relays by version

they did run when they were last seen):

processing [much] more data)

Disappeared relays by flags

(matches somewhat relays by flag graphs on metrics)
Flags appear in this order:
stable,fast,guard,exit,hsdir
