I had a similar fun experience when I was generating UUID subdomains and was shocked to see traffic in the logs before ever sharing the URL. I've since switched to a wildcard certificate but regardless, you can't really trust the hostname to be secret because of SNI and all that.
That would’ve been quite the surprise! I was initially shocked enough when @ and www were getting hammered. A fully random hostname would’ve dazzled me for a bit.
