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.

>>spiffy+c7
Yeah just coming here to say this. Multiple disk failures are pretty probable. I've had batches of both disks and SSDs with sequential serial numbers, subjected to the same workloads, all fail within the same ~24 hour periods.

>>bragr+Ya
Had the same experience with (identical) SSDs, two failures within 10 minutes in a RAID 5 configuration.

(Thankfully, they didn't completely die but just put themselves into read-only)
