I'm currently hosting the site with Nekoweb, which is basically a Neocities alternative. I mainly moved because Nekoweb's CDN support files over 300 MB, which helps with hosting my downloads since now I don't have to rely on third-party services that regularly shut my downloads down.

It's a piece of Javascript code that picks a random number and, from a list of possible strings, writes the chosen string from the list onto the page.
