I feel that somewhere up there Jon Postel is smiling about Matthew’s RFC 7514, published today:

The deployment of Explicit Congestion Notification (ECN) [RFC3168] remains stalled. While most operating systems support ECN, it is currently disabled by default because of fears that enabling ECN will break transport protocols. This document proposes a new ICMP message that a router or host may use to advise a host to reduce the rate at which it sends, in cases where the host ignores other signals such as packet loss and ECN. We call this message the “Really Explicit Congestion Notification” (RECN) message because it delivers a less subtle indication of congestion than packet loss and ECN.
