That someone would need to restore some backups, and in the meantime, use mirrors.
Seriously, not that big of a deal. I don't know how many copies of Wikipedia are lying around but considering that archives are free to download, I guess a lot. And if you count text-only versions of the English Wikipedia without history and talk pages, it is literally everywhere as it is a common dataset for natural language processing tasks. It is likely to be the most resilient piece of data of that scale in existence today.
The only difficulty in the worst case scenario would be rebuilding a new central location and restarting the machinery with trusted admins, editors, etc... Any of the tech giants could probably make a Wikipedia replacement in days, with all data restored, but it won't be Wikipedia.
That's small enough to live on most people's phones. It's small enough to be a single BluRay. Maybe Wikipedia should fund some mass printings.
What you do not get however is any media. No sounds, images, videos, drawings, examples, 3D artifacts, etc etc etc. This is a huge loss on many many many topics.
It's not a high bar.
Haven't we hit that point already with bad faith (and potentially government-run) coordinated editing and voting campaigns, as both Wales and Sanger have been pointing out for a while now?
See, for example,
* Sanger: https://en.wikipedia.org/wiki/User:Larry_Sanger/Nine_Theses
* Wales: https://en.wikipedia.org/wiki/Talk:Gaza_genocide/Archive_22#...
* PirateWires: https://www.piratewires.com/p/how-wikipedia-is-becoming-a-ma...
Yes, this is a real phenomenon. See, for instance, https://en.wikipedia.org/wiki/Timeline_of_Wikipedia%E2%80%93...: the examples from 2006 are funny, and the article's subject matter just gets sadder and sadder as the chronology goes on.
> and voting campaigns
I'm not sure what you mean by this. Wikipedia is not a democracy.
> as both Wales and Sanger have been pointing out
{{fv}}. Neither of those essays make this point. The closest either gets is Sanger's first thesis, which misunderstands the "support / oppose" mechanism. Ironically, his ninth thesis says to introduce voting, which would create the "voting campaign" vulnerability!
These are both really bad takes, which I struggle to believe are made in good faith, and I'm glad Wikipedians are mostly ignoring them. (I have not read the third link you provided, because Substack.)
