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.
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.
