Programming.Dev is going to be going down starting at around 00:01 UTC Monday Dec 2 to attempt to fix the database corruption that happened relating to communities.
This has been affecting attempting to look at the pages for certain communities (it would end up loading forever instead of actually showing the posts for the community) and was affecting federation in some cases.
This is the second attempt to fix the issues with the first one needing to be rollbacked from due to the fix not working.
This fix could take several hours, so the outage window is going to be from 00:01 - 06:00 Dec 2.
You should use /c/ and not /post/:
Ah, you’re right. I think I see what happened there, I hit those links from a sidebar in a community with href="imaginarywitches@lemmy.dbzer0.com"
which breaks if you’re on a post page instead of the community page. Easily fixed though, I’ll ping the mods of that community.
