When I search for communities about animation on the web interface, I see one called !animation@lemmy.film
There has been no activity in the /c for 6 months.
It's not my native instance, but I can read posts and comments in the /c, and I can even create a post in the /c.
But when I try to visit http://lemmy.film in a browser, I get a "Web Server Is Down" page.
Is the content in !animation@lemmy.film a ghost of cached content on my native instance?
The instance is down. Every instance copies the posts from the other instances when at least one person subscribes to it. So what you see is just the remnants of the instance on your instance.
