Hey guys,
I'm very very sorry. Let me explain what happend.
So we did some maintenance last night and we installed Hyper-V. Now what happend is, Hyper-V needs a virtual network adapter, that was done, but something went wrong and because of that the network adapter is failing.
On top of that, the KVM details we received with the server aren't working. And even more on top of that, the client system of the datacenter showed a blank page the whole night.
I was finally able to contact them, this should be resolved in a few moments. You will be credited for that.
Only the users on the 2 newest nodes have been affected.
Regards
