You can run this on your laptop and watch your WiFi drop in and out randomly (as other people around you download stuff, as Bluetooth devices interfere with it, etc.) It's also fun to run a speed test in another tab, and watch the latency increase 10x as needless buffers fill up and your latency-sensitive packets wait in line so your router gets a better review!
If anyone has a detailed guide on using gfblip I'd be really curious to read it.
Check out the instructions in the GitHub repository, has two versions, neither are very long nor complex. https://github.com/apenwarr/blip
After about 2 seconds of blue/green pings that seem faster than should be possible (<10ms), it goes full red.
It does work in Chrome! (Perhaps, Brave is doing some faster-fail on the probe request from the beginning, and then a cached-insta-failure after ~2 seconds?)
My blue pings to calgary are reliably ~2000ms then ~200ms. I wonder where in the chain that pattern is originating. I wonder if it'll stay like that over time.
Chrome also seems to show red dots every ~3 seconds for me, while Firefox shows no red dots, strange.
Tested on Ubuntu.
so browsers behave differently...
