Currently, if there are no running Selenoid instances behind ggr (or almost all of them are down), it takes a while until /status request gets resolved with some response. It's a bit inconvenient. Would be good to have some mechanism to sort these not running instances out and do not consider them in order to have more fast ggr-ui request-response logic. Once instance becomes available, it should be considered then. Any other suggestions to improve this would be appreciated.
