That's fair enough, I was comparing single-AZ AWS outages to single-DC Hetzner outages, since that seems to be what people are focusing on. For multi-DC deployments, I think laumars' sibling response to mine makes a much better argument—ultimately, you're still choosing who to pay and who to trust, and if things go down, there's nothing you can do to fix it. "Low-tech" cloud providers like Hetzner, Colo providers, amazon, PaaS—in a physical downtime event like this one, they're all the same.
Yes, Hetzner upgrades DCs (datacenter buildings), but they are the equivalent to AWS AZs (Availability Zones). When they upgrade a DC, they notify way in advance, and if you set up your services to span multiple DCs as is recommended, it does not affect you.
We run high-availability Ceph, Postgres, and Consul, across 3 Hetzner DCs, and have not had a Hetzner-induced service downtime in the 5 years that we do so.
