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.

I once had a small fleet of SSDs fail because they had some uptime counters that overflowed after 4.5 years, and that somehow persistently wrecked some internal data structures. It turned them into little, unrecoverable bricks.

It was not awesome seeing a bunch of servers go dark in just about the order we had originally powered them on. Not a fun day at all.

You are never going to guess how long the HN SSDs were in the servers... never ever... OK... I'll tell you: 4.5years. I am not even kidding.

Let me narrow my guess: They hit 4 years, 206 days and 16 hours . . . or 40,000 hours.

And that they were sold by HP or Dell, and manufactured by SanDisk.

Do I win a prize?

(None of us win prizes on this one).

These were made by SanDisk (SanDisk Optimus Lightning II) and the number of hours is between 39,984 and 40,032... I can't be precise because they are dead and I am going off of when the hardware configurations were entered in to our database (could have been before they were powered on) or when we handed them over to HN, and when the disks failed.

Unbelievable. Thank you for sharing your experience!
