HN was down because the failover server also failed: https://twitter.com/HNStatus/status/1545409429113229312

Double disk failure is improbable but not impossible.

The most impressive thing is that there seems to be no dataloss, almost whatsoever. Whatever the backup system is, it seems rock solid.

By second disk failure do they mean that the disks on both the primary and fallback servers failed? Or do they mean that two disks (of a RAID1 or similar setup) in the fallback server failed?

The latter is understandable, the former would be quite a surprise for such a popular site. That means that the machines have no disk redundancy and the server is going down immediately on disk failure. The fallback server would be the only backup.

The disks on both the primary and fallback servers definitely failed. Each was in a RAID setup, but those failed too in both cases.

Ouch! I'm assuming the disks were from the same batch and installed at the same time, but having at least four fail like that is just crazy unlucky.
