Hetzner is good, the hardware is (mostly) good, the provisioning is fast, the support responses are fast but they follow scripts very closely. The biggest problem is that their network is terrible. We typically lose contact (50% packet loss, 100ms latency) with a machine for 5-10 minutes every day. Different (groups of) machines, different times of the day and night. Every time, Hetzner claim it was an "attack".

I haven't measured it, but they're probably within the 99% availability (allows for 1.68 hours/week downtime) they advertise for any one machine.

Maybe my expectations are too high. :)
