Perhaps an interesting way to further qualify "highest web site" might be to demand it's available directly from the broader Internet. While even a permanent TCP/IP based device in space would be pretty cool (and, I imagine, actually exists) the cost of the connection is probably onerous to make it open to public use(?) So perhaps if someone could rig up a microwave link to a solar powered Raspberry Pi Zero hanging off of a weather balloon or something.. we could have a truly publicly accessible Web server at above jet-liner height? :-D This feels like something Tom Scott might try..
