zombo.com was launched in 1999. I remember in high school you'd see the new fancy web kiosk's the school put up just displaying it as a joke. and being locked out of the address bar so you couldn't change it.
The fact that this url has been renewed, maintained, and updated with all the advancements web browsers have made in the last 24 years, just to have this useless site still exist amuses me to no end.

That's one of the neat parts of the web-- it's very backwards compatible. Maybe they upgraded to https when that became a thing, but the maintenance costs of a site that small/simple are fairly low. Still, it shows that someone cares enough to keep it going!
I took a look, they updated their FontAwesome dependency sometime in 2016-ish and their site looks good on mobile. Looks like they do occasionally update it after all.
