[UPDATE 3/11 09:15] All login nodes are now online for a day or longer, hence we consider the problem solved.
[UPDATE 2/11 09:00] At the moment three of five login nodes are working. We are working on the other two as well and inform here when there is an update.
We are currently having troubles with the login nodes on Saga. Some login nodes are down or do not respond, hence logging into Saga is currently nearly impossible. We are investigating the reason for this. We will provide an update when the problem is fixed or we know what causes this.
We are sorry for the inconvenience this causes
