For folks following this here - node and neighborhood look clean. The issue appears to be a failing cable modem (MB8611 - they seem to suffer frequent disconnects when they fail). …

Several D3.1 modems support it now but most will need to be updated. Many of the vendors have been testing at quarterly L4S interop events, so I would expect them all to have produ…

UTP is intended to be less than best effort priority. This is about all the apps trying to share queues at best effort (1 level up).

I wrote a simplified summary of the IETF specs FWIW: https://github.com/jlivingood/IETF-L4S-Deployment/blob/main/...

It makes new cloud-based apps realistically & reliably workable - think cloud gaming and cloud AR. It also makes interactive stuff like gaming and video conferencing perform a lot …

See my comment above - doubt this will happen - rather it will become a differentiator like thoughput.

100% agree - read my IETF Internet Draft for more on that. :-) https://www.ietf.org/archive/id/draft-livingood-low-latency-...

> "Not sure where this leads but I guess ISPs will start charging toll for express lanes" Doubtful IMO. I think latency becomes another competitive differentiator, much like throug…

It has definitely changed. Looking at measurements on this it seems there is only 1 major transit network doing that, and they are working to fix it.

It usually means you are about to get a speed upgrade that will go beyond what your modem is capable of delivering. In that case it is possible you could have a 1st generation 4x4 …

What I meant in the context of that exchange was that the notifications come only after for example multiple emails have not resulted in the device being replaced.
