I don’t know the answers to your questions but there was a few hours outage a couple or so weeks ago. I’m not sure everything is totally back to normal since then. I think the search function is still acting screwy as an example.
All said it’s still better than not having FR around.
Must be because there sure has been a rash of multiple postings of the same articles - sometimes minutes apart, sometimes hours or days... often 3, 4, or more repeats of the exact same article from the same source...
