I’ve noticed that for one instance in particular (in my experience), feddit.uk, I am regularly seeing posts not federate properly. The most recent example I have found of this is c/britishproblems

If you compare:
https://programming.dev/c/britishproblems@feddit.uk
with
https://feddit.uk/c/britishproblems

You will see there are two posts on the home instance that have not federated to programming.dev, despite both being a month old.

Is there a technical reason that posts so old would not have federated in all this time?

Edit: I seem to be incorrect. The posts are not missing. The instances just show them in a different order (despite both being sorted by ‘Active’). I am an idiot.

I’ll leave this up as there may be some interesting discussion on how federation does / does not work.
