MediaWiki:Sitenotice:

• 2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored.
• 2025-11-09: More Mediawiki upgrade problems. I will dive into this when I get some time. Thanks to Exiled in Paradise for reporting. My external monitoring service told me things were fine.
