RFC 8516: "Too Many Requests" Response Code for the Constrained Application Protocol
In plain English — editorial summary, not part of the RFC
A Constrained Application Protocol (CoAP) server can experience temporary overload because one or more clients are sending requests to the server at a higher rate than the server is capable or willing to handle. This document defines a new CoAP response code for a server to indicate that a client should reduce the rate of requests.
