What kind of setup does HN have?

Checked HN’s official Twitter status page and it said there was issues with failing disks and such. But can we go into specifics here? Does HN’s servers use RAID? I would hope so.

I would hate to think this site is a fragile affair running on some low end box in a server closet with minimal attention to backups.

Read a few people joking on Twitter during HN’s downtime that HN should use Kubernetes and the latest cloud infra.

What setup does it have?
