This is actually pretty hard to do. We all have heard of internet rot/dead internet theory.

One shout might be to link to internet archive instead of the resource directly. Though we can't be sure internet archive will keep the current system working as is (e.g. search params may change etc)

The only solid solution I have is to set up a foundation and pour money in so that they will be responsible for upkeep. But that would be an hassle to execute.

100 years in internet time is very long, internet as we know it now hasn't been along for 100 years.

I wonder if there aren't services that specialize in this.

Have thought about this a bit. I think there's a "business model" where a non-profit foundation charges a very high price (say $50 or $100/gig) and the interest on that pays for the hosting and admin. One issue is startup risk, if you don't get enough people wanting to store data "forever" it won't be sustainable.

The foundation has a remit to also do some related "good works". The idea is that the pot of money (and the interest it throws off) acts as an incentive to keep the foundation going. Eventually the cost of hosting "legacy" data should drop close to zero. You could run it as an overlay on two clouds initially to avoid capital outlay.

I think you would want librarians / archivists on the board. It wouldn't require much in the way of software, making something that could last in the long term is more of a governance problem than a technical one.
