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.

It's not even improbable if the disks are the same kind purchased at the same time.

Yep: if you buy a pair disks together, there's a fair chance they'll both be from the same manufacturing batch, which correlates with disk defects.

Eek - now I'm glad I wait a few months before buying each disk for my NAS.

Not doing it for this reason but rather financial ones :) But as I have a totally mixed bunch of sizes I have no RAID and a disk loss would be horrible.

Have to be careful doing that too or you'll end up with subtly different revisions of the same model. This may or may not cause problems depending on the drives/controller/workload but can result in you chasing down weird performance gremlins or thinking you have a drive that's going bad.
