Why does this give a 404 error?:

That was a post that I made to a Lemmy community that was hosted by a server that has been down for over a month. Of course there is no direct access to lemmy.sdf.org, but fedia.io should have its own cached version. It accepted my post, I kept a copy of the link, and now the link is unreachable, even when I am logged in.

I suppose it’s another bug in mbin.

I’ve not seen that before. Is it happening every time you post?

    I have not tried to post a new thread since that one. But I suspect it’s related to SDF being down and perhaps also without having a subscription¹ to the community of the offline host. There is perhaps some fragility with mbin in that scenario. SDF is back online now after 2 months of down time, so it might be hard to reproduce.

    I would call this a relatively serious bug because it causes data loss. Luckily in my case I was just cross-posting from this original post, so no data loss. But if I had composed a high-effort post, all the work would have been thrown away. That link still today gives a 404.

    ① note that I was not subscribed to !opendata@lemmy.sdf.org at the time of the incident. But I just now subscribed.
