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.

Even if they're not the same, they're written at the same time and rate, meaning they have the same wear over time, subject to the same power/heat issues, etc.

Hopefully, regularly checking the disks' S.M.A.R.T status will help you stay on top of issues caused by those factors.

Also, you shouldn't wait for disks to fail to replace them. HN's disks were used for 4.5 years, which is greater than the typical disk lifetime, in my experience. They should have replaced them sooner, one by one, in anticipation of failure. This would also allow them to stagger their disk purchases to avoid similar manufacturing dates.
