  • There are two useful sections on https://status.lemm.ee for this - firstly, there is an automated check for federation with all other instances on the bottom of the page, and everything there being red is a definite sign that something is wrong with lemm.ee itself. Secondly, near the top of that page, I will always write a status message manually when I discover & start work on any issues. This second part can have a bit of a delay, as it requires manual input from myself, but I have updated it every time we had any issues so far.












  • I have identified two reasons for broken thumbnails right now:

    1. For some, the source website is simply not allowing our server to download the image (mostly due to server issues on the remote side)
    2. For others, it seems that some types of URLs are breaking thumbnail generation. I think I found the bug here and will try to submit a fix soon.

  • Regarding your question:

    Lemmy federation basically works by copying stuff from their source instance to all other federated instances. So if I write a comment on lemm.ee, other federated instances will get their own copy of my comment. They will also all know that the “authority” for this comment is lemm.ee.

    If an admin on another instance decides to delete their local copy of my comment on lemm.ee, then they are always free to do so (for example, some instances might want to moderate more strictly), but any actions they take like this are limited to their own instance - for the rest of Lemmy, lemm.ee remains the authority for this comment, so individual remote instance admins taking actions won’t have any effect on any other instances.

    As for the original topic of modlog federation, basically it just boils down to this: just like with the comment example above, Lemmy instances also save a local copy of incoming federated mod logs. The Lemmy software does not yet have 100% coverage in terms of federating mod logs (for example, there are no federated logs yet for instance admins banning remote users), but this coverage has been increasing, and I expect this will eventually get to 100% (just needs more dev time really).

    Also, if some instance admins try to tamper with their mod logs, then other instances can still see the real history, because there is no way for an instance admin to delete copies of their mod log from other instances.



  • Most actions federate, any exceptions which aren’t federated yet are generally just there because the federation logic has not been implemented (but improvements are constantly being worked on).

    Generally federating the modlog is mostly just there for informative purposes. As in, we can check what mod actions were taken on instance A through the modlog on instance B (and there is no mechanism in Lemmy for other instances to retroactively remove or hide federated modlog items, btw).
