Some (but not all) of the GIFs in the Rain World wiki are failing to load for some (but not all) users.
Examples: Jetfish
It appears that it's specifically the thumbnails for the GIFs that are failing to load. The requests to static.miraheze.org give a 302 response, and the new location at rainworld.miraheze.org has given me a few different errors including 502, 503, and 504. Examples of responses for the issue GIFs on the Worm Grass page:
On the File namespace page for some GIFs, the GIF itself loads fine but the thumbnails(?) don't load properly, whether the GIF is visible on the pages it's used in or not:
