I can't connect to Dardel at least since Wednesday evening, and the homepage (https://www.pdc.kth.se/) times out. Anyone else experiencing this?

I can connect to Dardel

There was a reboot of the login node a couple of days ago. I still can't connect, good to know that it's just me -- thanks!

Check your ssh key login hasn't expired. That was the issue I had last time. It's really not obvious that it's expired

Yes, that's a possibility. What's really puzzling me is that the homepage times out. Perhaps something with the SU VPN. I'll try without that first.
