Latest revision as of 10:50, 12 October 2018

Due to a massive power outage in Lugano (and apparently a big part of Ticino), most compute nodes of Euler went down at 10:42 this morning, causing the loss of all running jobs.

Since our colleagues at CSCS do not know when the power will be restored, we have initiated an emergency shutdown of all systems connected to UPS, including storage systems, login nodes and admin nodes.

We will update this page as the situation evolves.
