Does anyone have more context on why “unable to retrieve their xDS configurations.” led to ” Traffic Director-managed clients deprogrammed as the configuration was removed” ? For example, Envoy will keep its configuration forever unless 1) the configuration has a ttl or 2) the server itself sent back empty results. Was it the case that TD config uses ttls, the server was actually sending back empty results (frightening), or is this a behavior specific to grpc?

We suffered from similar issue to Spotify. Traffic Director pushed a mostly empty configuration to envoy. Very frightening indeed. It continued to push that invalid configuration over the course of the outage.
