Hi guys,

One interesting aspect of Lemmy being federated is that there are a lot of broken servers out there who constantly fails to federate. It can be anything that speaks activitypub really, and some of those servers are not properly federating, causing a super long queue of messages not being sent or received.

Ive been adding the most broken ones to our block list so we dont spend resources trying to talk to them. We are still federating with all activitypub servers that behave normally, so this is not about blocking instances that we dont like. This is about blocking broken ones only.

Just wanted to make a post about it so you guys know, in case you see that our instance is blocking instances now. Yes, we do, but only instances that dont federate properly. Otherwise we will continue trying to talk to them forever, wasting resources.

Thats it, just some info. Have a good week!

Yeah its interesting with federation. Just servers constantly chatting to everyone who knows how to talk using the activitypub protocol.

As soon as you hit a vote button or make a comment, its typically sent to every server, so there is a lot of chatting going on all the time. :)

There is a queue to keep track of weather or not messages have been received, so nothing is supposed to get lost also.
