>The silver lining is that our suffering helped uncover the underlying issue faster.
Did you actually uncover the true root cause? Or did they finally uncap the power consumption without telling you, just as they neither confirmed nor denied having limited it?
The root cause was a problem with the motherboard, though the exact issue remains unknown to us. I suspect that a component on the motherboard may have been vulnerable to power limitations or fluctuations and that the newer-generation motherboards included additional protection against this. However, this is purely my speculation.
I don't believe they simply lifted a power cap (if there was one in the first place). I genuinely think the fix came after the motherboard replacements. We had 2 batches of motherboard replacements and after that, the issue disappeared.
If someone from Hetzner is here, maybe they can give extra information.
