ue to vulnerabilities caused by hardware bugs in processors, my VPS kernel needed to be patched and my VPS would need to be restarted by my service provider.
As it was urgent, the email notifying me came basically at the same moment as the reboot.
I have restarted all my services, and the game should be back.
Sorry for the inconvenience.
