Below huge speeds, upload testing is done with web socket now,

so there is a websocket address on every server now anyway.

The baseline pinging to dslreports.com doesn't seem broken

but if necessary it can be changed to baseline pinging to the

nearest server, wherever that is.

Personally I might be skewed by using Firefox on Linux, I don't see the awesome live bloat-meter, only the awesome bloat graphs.

PS My firefox also doesn't show the new graph-based speedtest history. I disabled the obvious culprits (noscript, ghostery, ublock) & there's nothing on the JS console. Happy to help if needed.

"Fixing" the bufferbloat ping graph would make it more directly comparable to the pings on other speedtests. I think that makes the bufferbloat point clearer. Again the issue is outside the US; in the UK I see a 100ms "baseline". If it's simple to start using nearer servers, that would make me very happy :).

I agree it's not "broken". (I also use netperf-eu at 59ms). It's just confusing to interpret, if you don't already know what bufferbloat is going to look like.

Particularly as the "expected" low ping value shown at the start. The 100ms server isn't even shown on the ping radar part.

If it's easier to just call out the destination country on the bufferbloat ping, or fudge the figures convincingly (just graph the increases from a minimum), that would answer my point too.

Good fun :).

The baseline latency is because the bloat measurement uses a single websocket ping server in America. Justin said in the forums it didn't seem worth the effort to set up more of them. Seems worth an faq item though :(.
