These days one can register a domain for ten years, and have it auto-renew with prefunded payments that are already sitting in the account. This is what I did for the URL shortener I am developing.
The same would have to be done for the node running the service, and it too has been prefunded with a sitting balance.
Granted, there still exist failure modes, and so the bus factor needs to be more than one, but the above setup can in all probability easily ride out a few decades with the original person forgetting about it. In principle, a prefunded LLM with access to appropriate tooling and a headless browser can even be put in charge to address common administrative concerns.
