Yggdrasil seems down


Username: $solfrini
Cluster: $Yggdrasil

I’ve been trying to connect to Yggdrasil since this morning but the server seems unresponsive (the SSH connection times out). The Grafana Dashboard seems to be down and OpenXdMod shows no resources utilisation.

Is there any problem with Yggdrasil?
Thank you in advance.

Have a nice day,


Hi, I have the same problem.

Hi, I have the same problem since the morning of Dec 9.

I can confirm that the cluster is not available, too.
I have heard for one living at the observatory, that there was a blackout. While power is back, the internet connection was still be down. It might take more time for the observatory IT group doing a successful reboot of all the connections.


It seems that the problem still persists. Attempts at logging into Yggdrasil yields the following error: ssh: connect to host login1.yggdrasil.hpc.unige.ch port 22: Network is unreachable. However, there’s no issue logging into Baobab.

Kindly rectify the issue when possible.
