Infinite loops between servers are something that must be carefully avoided to prevent performance degradation or network overload.

In light of the heightened awareness of this attack vector, now is a good time to discuss looping behavior which impacted our implementation of QUIC and review the postmortem action items that followed each event. Our experience diagnosing and mitigating attacks, as well as deploying fixes, may assist others attempting to address similar threats.

Never would have guessed layering multiple protocols on top of UDP could result in collisions.
