I recently wondered, and I assume the answer is on the website that is currently down, about what guarantees that Web Archive will survive longer than your standard website?
What makes it an archive in terms of longevity? Is it backed by governments or NGOs? What if the funding stops? Etc.
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/
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.
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.
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)
Since a dead link doesn't reveal much: this outage appears to affect just the Wayback Machine. The other collections appear to be accessible through http://archive.org
