I don't know any context or background but if you fear this could happen to you again, I recommend to use tor's OfflineMasterKey feature (without copying the master key to the server) with a short keylifetime (i.e. 7 days), especially if it is a fallback dir (which requires a tor source code change to remove it).
Thanks for this feature, I don't know it !
If you want to use it you likely want to automate that especially with a keylifetime of < 30days because copying around files manually every week is no fun. ansible-relayor does that out of the box for you ;) https://github.com/nusenu/ansible-relayor
Could you also confirm the relay fingerprints (in addition to the nicknames)?

thanks for the fingerprints.
Did you shutdown kitten3/4 (yoda.imirhil.fr) 3F5D8A879C58961BB45A3D26AC41B543B40236D6 6FB38EB22E57EF7ED5EF00238F6A48E553735D88
yourself? (last seen Monday 2017-05-15 11:00) or did Online SAS cancel this second VPS after the first one got seized?
thanks, nusenu
