Nice, ha? Mostly it's just a funny feature I implemented, because I ping my server list one time a day. So sometimes a perfectly alive server gets marked dead when I can't reach it at that exact moment.
But I have to say, that around 10% of the servers which were alive around the hype 2017/18 gone down.
Nevertheless it's fun to look around. There are so many gems to find, you'll never find on the WWW.
Besides that gopher makes fun to host from your living room.
