It's colocated hardware, with a thin service layer on top so they set it up for you as a service. The service and hardware are quite reliable, but you can (and will) still lose all your data in case the hardware fails. You have to create your own processes and layering to get to an adequate number of 9s for whatever kind of reliability you're looking for.

After the launch of Hetzner Cloud six months ago, Block Storage and Object Storage might be on their way[1].

"but you can (and will) still lose all your data in case the hardware fails. "

Can you elaborate this? I mean besides if the center burns down? They offer "snapshots". If the drive fails, they can not recreate the last snapshot?

I suspect these are like ZFS snapshots -- they're not backed up, but allow you to restore your data to a previous point in time (like git history).

I think that basically the guarantee exists as long as the raid array within the box is operating. There's no other safety.

Unless I'm mistaken (entirely possible), it's not colocated hardware -- Hetzner own both their data centres and the hardware in them.

Right, I meant to say it's "like colocated hardware". Hetzner own the hardware, but the service guarantees are similar to where you own the hardware. If the hardware fails, tough luck.

Big power outage in May (at least on some dedicated servers).
