Noob question: if I rent one of these dedicated servers, what happens if some hardware fails? Do I need to contact support or will they detect that automatically? If something needs to be fixed manually (e.g., hard drive, cpu, network), how long does one need to wait for dedicated servers? I'm used to cloud VMs where if one dies, I can quickly spin up another one effortlessly (I never have to contact support or anyth…
Hardware inside server is up to you to notify Hetzner. After more than 10 years never have an issue but disk degradation after many use. Then you contact support, appoint disk change, you first deactivate disk on raid (save geometry etc), they replace disk and then you rebuild raid in new disk. That's it. With SSD you may not even need to do this anymore.
I imagine this would take time, right? Like not 5 minutes, but maybe 3 hours top? So, if I pretend to run a saas (that shouldn't be down more than 1h/day), then renting only 1 dedicated server could be qualified as "risky"?
