Well, a couple of things.
The last time source.squeak.org was down was May. At the time Ken accessed the Hetzner robot to reboot the server. I have an email saying he got access from Marcus.
I ssh'd into box2 and the squeakso process (seen with top -d 3) is now <defunct>. I think this means it is now a zombie having no parent process and that the problem can only be solved with a reboot.
Somebody needs to go to the Hetzner robot and flip the "reboot" switch. I would also point out that is is Thanksgiving in the USA, but not in France. I think Ken will be out of the picture for days. If somebody could contact Marcus (he's cc'd above) to flip the switch, perhaps that would be a solution.
