There are also plenty of other wifi connection test domains [1][2] around that he didn't have to buy one.

Apple returns "success" 200, opensuse returns 304 (no-content) and may close the browser tab instantly so you have to fiddle in console to see it working.

  await fetch('http://conncheck.opensuse.org',{mode:'no-cors'})

Strictly speaking, I have enough garbage domains that I could have used any one of them, but when I found a cute short name I grabbed it. ... Hosting it myself means my computer doesn't tell someone additional where I am all the time ... Although since the requests are plain http, that doesn't really mean much.

Also note:

That LF at the end means now I need to figure out how to get that into the registry (maybe it's trivial but it takes an additional ΔT and ΔW.

As for the opensuse one, I am not sure if the check works with empty content. Again, not hard to figure out, but additional ΔT and ΔW.

Plus, these sites can change whatever they do at any time and if I customize to match them, then I am at their beck and call as opposed to controlling both sides of the equation.
