UPPMAX was shutdown on Monday at 13:00 CEST due to loss of cooling closed

We are currently having an issue with cooling in the computer hall. If we soon do not make any progress to get the cooling back we will be forced to shutdown our systems. This affects all UPPMAX systems.

Final ticket report

All systems are up and running after the ångström wide cooling failure.

At around 12:48 our computer room lost cooling due to failure of the Ångström cooling curcuit. The cooling failed because the controlling system was disconnected by mistake by one of the contractors involved in building the new Ångström houses.

The temperature then started to rise about 1°C per minute as you can see in the picture below and the situation quickly became critical.

Here is a short outline of what happened:

According to Akademiska Hus they have staff on-site to help with the cooling issue that is, as far as can tell, still an issue but under control. We have not yet received information what might have caused the cooling to stop. We have begun restoring our systems but we do not yet have an ETA.

Update 2018-06-18 14:41

All systems were shutdown around 13:00. We are waiting on confirmation from Akademiska Hus that the problem has been fixed.
