We have our first production node running vpsAdminOS in Prague: node1.prg.
It's mainly intended for new members and new VPSes. We can migrate Prague production VPSes from OpenVZ on request, but for now only by individual arrangement through support. vpsAdminOS will reach Brno later; only OpenVZ remains available there.
Staging will continue as before. We aren't currently moving staging VPSes to node1.prg, even on request. We'll get to that in the coming weeks and notify everyone affected.
From now on, we have two virtualization platforms in production in Prague. Keep that in mind when using the NAS and playground. Playground is now only for OpenVZ VPSes; Staging serves that purpose for vpsAdminOS. For more on the differences, see our KB documentation.
