ngl my programming career helped me stay grounded in reality. Every impossible issue turned out to always have a cause, a reason to be there. Could have taken weeks to track down the issue, but there was always a cause.
But still.. every 3 or so years.. something actually impossible pops-up. Impossible to fix, impossible to reproduce, and suddenly gone from existence, as if it was never there.
Well at least some of the Jenga towers have redundant Jenga tower replicas, and that Jenga tower over there has a bunch of other Jenga towers ready to be propped up by a PAASser-by given a small cold start penalty. And this one? Nobody knows how it works, but it always worked.
Yeah. First instinct in this case makes me think somebody that owns a product upstream saw a failure log and fixed the issue (I'd still want to confirm that, though)
