@julian It Depends™, but even just saying something like:

"A receiving server MAY return a 429 on a request. If this happens or if the server cannot be reached the sending server SHOULD retry with exponential backoff. They SHOULD have a period of time after which they will stop trying and SHOULD have a period of time after which they will consider the actor 'dead' and stop sending them messages."

Instead you get things like these:

For federated servers performing delivery to a third party server, delivery SHOULD be performed asynchronously, and SHOULD additionally retry delivery to recipients if it fails due to network error.
