This is an issue with lemmy.ml, not lemmy.one. Lemmy servers are responsible for sending information out to other servers, lemmy.one is not responsible for pulling information in.

If lemmy.ml is not federating your community posts or your community there is broken entirely (which it sort of looks like…) then they have to fix that, or you have to rebuild a new community on an instance which isn’t broken.

Are we observing lemmy.ml having slow-downs or congestion problems?

Absolutely, even now I just opened lemmy.ml in a web browser, and the page half-loaded without any styling. Their instance is not functioning reliably in general.

Is lemmy.ml properly federating with us? Is that something you can check? Are we observing lemmy.ml having slow-downs or congestion problems?

I’m having similar problems where the subscriptions to the communities on lemmy.ml are still showing as “Subscription Pending”.
