If you troubleshoot your ISP based on speed tests you will be chasing

pushing more a dozen ways (including a speed test).  The only thing
lacking is a latency measurement of some sort.  Preseem and Libreqos's
TCP measurements on the head end are awesome, but that's not available
on the subscriber's side but if it were, there's the full testing
suite.  how much peak data, what happened to latency.  If you could
get data from the ISP's head end to diff you'd have internet vs isp
latencies.    'speed test' is a stress test or a burn in test in
effect.


I cannot upvote this enough. I call speed tests — and in fact any packet
injection doing more than a bare minimum probe — destructive testing, and
said as much to NTIA recently.

The *big problem* (emphasis mine) is that the recent BEAD NOFO, pumping
tens of billions of dollars into broadband, has *speedtests* as the "proof"
that an ISP is delivering.

It's one thing to solve this problem at the ISP and consumer level. It's
another to solve it at the political level. In this case, I think it's
incumbent on ISPs to atone for former sins — now that we know that speed
tests are not just bad but actively misleading, we need to provide real
tools and education.

Going back to my previous comment, and no disrespect meant to the CAKE
autorate detection: "How do we distinguish between constrained supply and
reduced demand *without injecting packets or layer violations*?"
