Dear Customer,

At this moment you may experience a failure in our “Dedicated Servers” service(s), servers on dedicated server pool 10 are unreachable.

Our technical crew is currently investigating the source of this problem. We will post an update as soon as we have new info.

Our well-meaned apologies for any discomfort.

23:10: The raidcontroller of dedi-pool-10.kvm isn’t working properly. We will replace the controller a.s.a.p.
