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)

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:

In your /16 netblock ( 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
