Post #1374148

Ok, not a deep mystery: the Mastodon backend does use the Rails cache (which I presume is in-memory, not persistent) to hold onto the result for up to 24 hours: https://github.com/mastodon/mastodon/blob/main/app/services/translate_status_service.rb#L18 Still involves network traffic clientside, but it's not like that feature hammers a remote service.
