Investigating a video streaming failure consists of inspecting all aspects of a member account. We took a hybrid head-based sampling approach that allows for recording 100% of traces for a specific and configurable set of requests, while continuing to randomly sample traffic per the policy set at ingestion point.

As such, tuning congestion logic is usually only done by a select few developers, and evolution is slow.
