Contrary to what some people might have thought, the CodeWalrus Minecraft server, located at http://mc.codewalr.us
, is still in operation. It just has terrible uptime.
The only catch is that now that Juju has moved, if the server goes offline then it is only re-opened on-demand, meaning that you have to bug @Juju
about it. Also, it requires a Minecraft version from the early 70's and it's world-edit-based creative rather than survival, but our affiliate BosaikNet
runs a survival server for those who prefers that.
