Well, then it should be a 5xx, not a 4xx, as the problem is not related to
the client's request but to the server's operational condition. Probably
that this 444 was randomly picked as handful at that time without much
preliminary thinking. I observe that 4xx and 5xx are often mixed in field
and that's pretty concerning, because it makes troubleshooting much more
