Doing this during a Windows 11 install will result in a road block until you fix said connection issues. You literally can't proceed without finding a hidden terminal and disabling the process and restarting. Insane.

Doing what? Blocking those domains?

Given the sheer volume of connections to the test servers, wouldn't it make sense to have the content of the text file as minimal as possible? Such as "1" or "OK".

21 bytes extra at 1T requests a day = 21TB/day. Probably nothing?

HTTP is also pretty inefficient. I guess if you went for some sort of custom protocol it could be blocked by firewalls or whatever.

Is it a problem that the URL is not HTTPS or is it the blessing required to defeat it?

One reason for that is explained well in a comment on the article.

Note that as with the Windows version, the protocol is HTTP, not HTTPS – because captive portals completely break TLS, but plaintext HTTP will result in a clean redirect to the portal, allowing the network service to detect the presence of the portal and to bring up a browser window to let the user authenticate.

I can see no reason why HTTPS is needed in any event. It's a single purpose domain that serves a static text file which everyone knows the content of.
