Sorry for bringing up this old topic, but it discusses a question about IPFS for which I cannot really find a clear answer. I browsed through a number of discussions on this topic and decided to post my comment.
As I understand so far, this is how it works (please correct me if I’m wrong). For example, I share a file on IPFS and only one other node downloads or pins it. If after some time that node decides that it doesn’t want to provide storage for that file to keep it locally and deletes it, and my node happens to be offline, then no one else can get the file.
If this is true, then the permanency of this kind of Web is not guaranteed. Similar to BitTorrent, if there are no active seeders, you cannot get the file.
Therefore, if no active nodes provide access to the file, does it mean that the hash becomes broken? Similarly to http:// link becoming broken if server error occurs?
Could someone please comment on this, is this correct or am I missing something?
