It seems the error has been fixed.
I was one of those who complained about the incident, and I had even canceled my plan. The disk was simply showing 0 to 5 IOPS, but it was resolved last night. Something I've noticed is that they've now set a disk speed of 50k IOPS. Before, one client could get 70k or more IOPS, but it could also cause others to have less. I didn't know if it was disk sharing or what. Apparently, they've assigned a fixed number of IOPS, which I think is better. I haven't seen any announcements about this new measure. I really hope they continue to improve. I've been with Netcup for about four months, and this was the first incident. Besides them, I have sites with five other providers, so I'm not someone who uses support unless it's something really serious. But it's good that they fixed the problem. I'll keep checking this week to see if everything is still working.

I'm experiencing exactly the same issue with my root server. The performance drops massively for a few seconds at irregular intervals, which is causing problems for our production system as well.
I've also opened a support ticket with Netcup (Ticket NCSUP-1032814). Hopefully, this helps to raise awareness of the issue and gives others affected by the same problem some additional context.
