Maple leaves are still dropping

And why did it take almost 8 hours again? >.>

My guess:
It was supposed to be a server update ("patch" - but only server-side).
Something went very wrong.
Somebody decided to go back to the previous version of the software, rather than try to fix whatever was wrong on the fly.

That's why we don't see any change at all - neither bug fixes nor the simple, expected, disappearance of maple leaves and notebooks.

However, it doesn't explain why the Rankings stopped working on those servers where they did work before.
