In general 4xx errors are problems with the request, and 5xx errors are operational issues with the server/network

  Too continue. It's "you're sending ttoo many requests" not "server is overloaded/getting too many requests". Hence it's a client error 4xx, and not server 5xx.

    Put that way, it makes sense. Thanks.
