Checking in again, as I have the feeling the bulk of Commons media (~300 TB in all) is not mirrored anywhere right now.
1. WikiTeam, we love you, what do you need to be more effective at archiving WM wikis?
2. Are there any commons media dumps more recent than 2016?
I saw something related mentioned on phab? within the last year, but can't find it now.
It seems like a good plan like to ensure a quarterly snapshot is on IPFS [via the Internet Archive],
and to keep a copy in the moon archive + others.
