Just in case you want a another point of reference to eliminate weirdness with the specific box: http://de.kl.wtf/f/10mburandom
Linode Arch Linux box in Frankfurt, serving you with a pretty standard usage of Go’s http server. Should count as a “stock linux box with a non-weird HTTP server”. if you add an “s”, you get TLS. If you add a “0”, you get 100MB. If you remove a country code, it goes through Cloudflare. You’ll have to guess where to insert and remove those characters yourself, though!
