Used to have nginx point the default location to an abyss web server, but I didn’t carry the setup forward when I upgraded the OS. It’s a 503 now.
Several other locations are pointing to:
my homebrewed file server. Initially to replace abtssws’s piss poor directory listing performance, but now a frankensteinian being that has a comic reader of my own specs and preference
an icecast server streaming whatever my foobar2k is playing, so I can listen to my library on the go.
