Yep :) I just find example.com easier to remember and quicker to type than any of the OS or browser makers own URLs like
- http://connectivitycheck.gstatic.com/generate_204
- http://detectportal.brave-http-only.com/
Plus, it feels nice to depend on the reserved domain name example.com instead of relying on a domain that any one specific corporation has to maintain :D
Also http://detectportal.firefox.com. And http://neverssl.com was set up for this purpose while being a bit easier to remember :)
I remember a while back neverssl.com would happily serve HTTPS requests! Another good alternative is http://httpforever.com/
