The server was unreachable for 3 hours between 19 and 22 CET this evening. A short disruption in the power (less than a second) seems to have caused the modem to bug out. A restart helped and we’re now finally back online! The server did not reboot, the UPS did it’s job for once 😉
Update: The server was unreachable again between 00.00 – 08.50 CET because of the same problem.
Update2: The connection went down again almost immediately, unreachable between 09.20 – 14.10. I think it should stay up this time, and the short freezez should be gone now.
