I've been thinking about this too. It should be backed by a p2p network to be resilient. But probably there are mirrors, they are simply not advertised for security? (plenty of copyright infringement on archive.org)

Their infrastructure is explained in this talk: https://www.youtube.com/watch?v=neBeDgICOeA

I’m not overly hopeful. I suspect the ‘COVID’ library ends up getting…expensive, at best.

I used to work in Web preservation and we often discussed/collaborated with internet archive.

I was working in a French government-funded Web preservation project.

Many countries have such government-led projects (france, norway, iceland, italy, usa - via the library of congress, slovenia). For a full list of who does that, see https://netpreserve.org/

Short answer: partial replication of the data at other institutions + overlap of the archive at other institutions

Many projects like internet archive exist, they are not necessarily publicly accessible via the internet (in France the archive can be consulted from public libraries via dedicated computers).

If you are interested in the topic, also take a look at the LOCKSS project from Stanford: https://www.lockss.org/

How does replication in the EU work with right to be forgotten laws?

There are public interest exceptions to European right-to-be-forgotten laws.

Cases are handled on an individual basis. Sometimes those exceptions apply, sometimes they needs of the individual supercedes the public interests.

Is there an existing service where I can query an URL and get a list of preservation projects that have successfully archived that URL?

There are a few browser add-ons that will list about a dozen archives for every page you visit. However, that doesn't include non-public services like the one mentioned above.

You are looking for Memento.

- http://timetravel.mementoweb.org/ (search seems to be down)

- https://www.webarchive.org.uk/mementos/search (search not responsive for me)

- https://mementoweb.github.io/SiteStory/redirector.html (protocol and tools)

That’s why they’re collaborating with IPFS, a p2p content addressed file system

I haven't been able to figure out how to access the IPFS versions of the archive. They technically have a version of their site hosted through IPFS (https://www-dweb-cors.dev.archive.org/web), but when searching for a specific url like nytimes.com, it just redirects to the standard archive.org url.
