Not that I’m aware of.

Have previously seen similar things posted into communities such as !lemmy@lemmy.ml and !fediverse@lemmy.ml but it would be nice to have a dedicated one IMO, probably a sister community for one of the lemmy status sites

• https://lemmy-status.org/
• https://lestat.org/

This is legitimately a great idea. I recommend putting it on lemmy.ml to start with as they are the closest we’ve got to a flagship instance. Would say lemmy.world if they weren’t down all the time

I’ve now created such communities (on several instances to provide redundancy):
!isitdown@infosec.pub
!isitdown@lemmy.world
!isitdown@lemmy.ml
!isitdown@feddit.de
!isitdown@kbin.social
