This bloke in his Hawaiian shirt says that UBNT has cake in the access points to manage clients: https://blog.apnic.net/2020/01/22/bufferbloat-may-be-solved-but-its-not-over-yet/
Yeah, again the only reasonable place that a router can affect scheduling as a CPE, is on the uplink. So yes, in this case the pings look great, because likely the outbound scheduling was more prioritised for ICMP on the outbound portion.

For a WiFi AP, if it has cake, or fq_codel baked in it can probably determine based on retransmits etc, what kind of "signal" and maximum download a client on the UBNT WiFi AP can handle. But as far as the router going to the ISP goes...

Without the cooperation of his ISP, his inbound is still 99% limited to whatever queueing mechanisms his ISP employs. So, cake baked into a UBNT AP simply solves a LAN issue, which is not always bad, but also not something your ISP cares about a lot. :laugh:

The goal of the bufferbloat project was to “hold latencies low or constant, no matter how much bandwidth you have.”

True only for the upload/outbound. Inbound cannot be controlled in a CPE, no matter what queuing it uses, as the packet has already arrived, in the priority and buffer/delay determined by the ISP termination kit. fq_codel is still way too CPU intensive to employ in an ISP NAS, in general.

I am seeing similar higher than normal latency on a trace to 1.1.1.1 - this is on Openserve in Cape Town:

@PBCool @TheRoDent is there anything that can be done about the ~20ms latency to Cloudflare DNS- this is for Openserve Cape Town. I would guess that this is related to my current WAN IP address? This Smokeping chart indicates a change on the 22nd, which happens to coincide with when I took my home network down on Monday for some maintenance:

Traceroute to 1.1.1.1 from my router:

This might be an odd question but is it normal for twitch to pull streams from what I assume is Hong Kong (hkg)?

Your latency over the Openserve network is not a simple advertising issue, we pickup your traffic at Teraco Isando, that last mile latency is imposed on Openserves network which will take some escalating.
I'm gonna ask around for a few test accounts in the meantime.
