Not the original question Rob asked, but a year ago there was a session
and the (reformatted) notes contain:

longclaw: hongkong -> US
moria: US->US
matuska: .se->us
faravahar: us->us
sebastian: de->de 

https://trac.torproject.org/projects/tor/wiki/org/meetings/2017Amsterdam/Notes/bwauths

(I don't know why there is a sebastian instead of a gabelmoo).

Obviously the situation has changed a bit since then. I don't know if
any of the bwscanner locations changed, either (not including losing
longclaw and sebastian and adding bastet).
