We're aware of ongoing federation issues for activities being sent to us by lemmy.ml.

~~We're currently working on the issue, but we don't have an ETA right now.~~

Cloudflare is reporting 520 - Origin Error when lemmy.ml is trying to send us activities, but the requests don't seem to properly arrive on our proxy server. This is working fine for federation with all other instances so far, but we have seen a few more requests not related to activity sending that seem to occasionally report the same error.

~~Right now we're about 1.25 days behind lemmy.ml.~~

You can still manually resolve posts in lemmy.ml communities or comments by lemmy.ml users in our communities to make them show up here without waiting for federation, but this obviously is not something that will replace regular federation.

We'll update this post when there is any new information available.

Update: Federation is resumed and we're down to less than 5 hours lag, the remainder should be caught up soon.

The root cause is still not identified unfortunately.
