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 !
Could you also confirm the relay fingerprints (in addition to the nicknames)?
