The uptime was just now 9h 30 min, so it restarted at least then. Please PM me, when you noticed that the list server ist down.
EDIT: There server is up, but I cannot get a response. However, I can connect to the SVN. Maybe node.fs did not liked the last upgrade. I will investigate tomorrow, as midnight has already passed here.
EDIT2:
The last node.ls update (or server update) barred port 80 for unknown reason. It now answers again, but it main no recieve any announcements. Still working on it.
