I've decommissioned bugzilla.icculus.org.
It hadn't had a real new bug in over two years. The heaviest users of it (myself, OpenBox, etc) had long-since moved on, so it was just collecting the occasional spam. But at this point even most of the spambots were like, dang, that's some old stuff, let's not waste the bandwidth.
The two most important URLs (view a bug, download an attachment) still work, thanks to a little project I threw together called static-bugzilla, so the most crucial[^2] links around the web will continue to work, even though none of the actual user interface of Bugzilla is available anymore.
But hey, at least we can now still relive the never-ending KIntersect bug nightmare, if we are feeling really low one day.
