On Monday evening (19.11.2011) around 18:30 a power outage in the HIT server room shut down most of our core infrastructure servers. Apparently the building automation system had turned off the cooling in HIT D 13 and when the temperature in the server room reached 37C, there was an emergency power cut. After the electricians had restored power around 21:00, we started bringing our servers back up. Around 23:00 most of the services were back, with the exception of the main web server which we managed to recover on Tuesday around 9:00. Also webmail took a bit longer.
We apologize for any inconvenience.
