Outage of Servers in Serverroom ETZ/D/96.2

Status: Status/green.gif

2017-10-20 13:45
All racks in ETZ/D/96.2 are working again (cooling problem solved).
2017-10-20 10:00
The technician will arrive at 13:00 hours. Some servers are running, but without watercooling. So any rack might shutdown at any time if the air cooling is not sufficient. This will most probably again happen when the technician will be working in the room (i.e. this afternoon).
2017-10-19 18:30
The cooling engineer could not fix the problem, so some servers are still offline. Another technicial will try to fix the cooling system tomorrow morning.
2017-10-18 14:00
Cooling system is still not working correctly, we only selectively powered on a couple of compute machines.
2017-10-18 12:50
The problem has been localized and repaired. We need to wait that the circuit is cooling down.

Outage of most racks in ETZ/D/96.2 (cooling problem) . Most compute servers are offline.
