Tobias Sachs:
Hetzner hosts > 7% of the tor network capacity (#3 on the biggest ASes on the tor network).
their actual fraction might be even bigger because I used onionoo data to attribute relays to specific ASes and onionoo didn't switch to a better IP->AS number source yet (so some relays have missing AS level data like yours as you can see on Relay Search)
https://trac.torproject.org/projects/tor/ticket/26585
If I know the relays IP I could give you the probabilities of your relay relaying traffic to others in the same AS (since a relay will usually not be used with others in the same /16 netblock)
So that means the same-as protection is a check that it is not the same /16 Block? That would make sense.
I'm not sure what you mean by "same-as protection", do you want to elaborate?
Hetzner is holding 17 /16 and smaller netblocks. So it is possible that the complete route is within one AS? o.O
The (BGP) routing itself does not have any affect on the /16 netblock rule in tor.
The IP is: 159.69.2.239
In your /16 netblock (159.69.0.0/16) there are only 7 relays with a total of 0.169% consensus weight fraction (so the fraction of this should not really matter compared to the overall fraction of Hetzner)
btw: please set a proper MyFamily on your relays https://metrics.torproject.org/rs.html#search/contact:0x4cf76925833e2e24
