// The log for a request is typically available within thirty (30) minutes
// of the request taking place under normal conditions. We deliver logs
// ordered by the time that the logs were created, i.e. the timestamp of
// the request when it was received by the edge. Given the order of
// delivery, we recommend waiting a full thirty minutes to ingest a full
// set of logs. This will help ensure that any congestion in the log
// pipeline has passed and a full set of logs can be ingested.
