thanks for trying to help but it looks like none of those nodes are working.. I'm still getting no block source available using the latest client 0.1.2 downloaded directly from the Primecoin website.
i synced 15 weeks of blocks for hour and a half thru those
check your time - it needs to be correct and synced
check your network - your router/firewall have to have UPnP, or you manually have to open port 9911
the problem is not in the network, just downloaded official client and started it clean, 10 seconds later it have 8 nodes and syncing
