503 UC does not get reported as a span.
Where a connection failed, a span is not recorded in Jaeger. From a users perspective this results in us seeing metrics for failures (503's) then going to try and investigate them, and not finding any spans.
Description: More details are on https://github.com/istio/istio/issues/50875, I was just asked to raise it here.

hmmm, I believe in normal case the span should be created and reported. Is your request a request from downstream or side request that created by the async client of Envoy?

Sorry I never got back to you here, completely missed the question.

The span does not get recorded when the connection to an external host here gets a reset, eg upstream reset: reset reason: connection termination.
