"Amazon is cutting Prime Video streaming bitrates in Europe"
"Netflix and YouTube have made similar decisions in the last 24 hours."

One of my friend in the business claimed that Netflix has actually asked NBC to stop broadcasting in HD.  I have not looked into that so I cannot confirm it.

These are examples of feedback that will dynamically alleviate congestion.  Very interesting.

We are very used to low latency phone calls… and users unable to interrupt are often unhappy with buffered solutions.  We often chose to drop packets, sometimes a LOT of them, to preserve the call session and avoid buffering.
