This is a very inopportune moment, but it seems that CSZO vanished from the Internet this morning. The maintainer Amethyst opened an emergency ticket with the ISP a few hours ago; there has been no response yet.
Update 2014-04-16 14:43 UTC: The ISP says they are having technical difficulty with their fiber connections to two upstream providers, and have been working on the issue since it started about eight hours ago. Several customers are experiencing problems, not just CSZO. They expect the network to be “back up and running soon”. -neil
Update 2014-04-16 20:55 UTC: The network is back up, but there is still some packet loss for the time being, so expect some lag until everything is fully resolved. -neil
