> Something that would be interesting to see (particularly if someone has eyes in Comcast’s network) is to see how customers in areas where L4S trials are happening faired in comparison to others.

The sample area of the deployment is still to small from which to draw conclusions (~20K homes). We’ll know in a few weeks more how things look in comparison. But in this example, I think the bottleneck was more likely on the server/CDN side of things, so CPE and last mile AQM and/or dual queue L4S would probably not have made a difference. But never know without knowing full root cause. I have no doubt the Netflix folks will sort it – they’ve got some very smart transport layer and CDN folks.
