IPFS is not a real solution at the moment. It's hard to use it, the default daemon is so agressive Hetzner nearly blocked my server due to it's scanning, and your site needs to be relative-url based to be put on IPFS.
On the other hand, nobody is talking about the problem of domains: yes, linkrot is a thing, but many are due to dead domains and dead blogging/content silos.
I've had to deal with Hetzner and IPFS too -- my conclusion is that it's Hetzner who are aggressive here. In of the cases I had fixed the dialing-local-networks behaviour, and then Hetzner still continued to block the server for about a week. They blocked it on 25-Dec and released it on 31-Dec.
