I've had way more networking and availability failures from Hetzner this year alone then I've ever seen from AWS. They regularly replace their networking switches without any redundancy, leaving entire DCs offline for hours. They're okay for hobby projects, but I would never host a business-critical site with them
- nh2 5y agoCannot confirm, do you have details? 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.
- nightpool 5y agoThat'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.
