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.

If you have an active/passive HA setup and don't test it periodically (by taking the active server offline and switching them afterwards), my guess is that double disk failures will be more common than single disk failures for you.

Still, I see no reason for prioritizing that failure mode on a site like HN.
