#2I suppose that’s true. But it also occurs to me that their ops team is not your ops team, their observability stack is not yours, etc.
I work for a company that’s fairly well known here. I can’t recall us having an outage (or something less severe than a full outage) that was our cloud provider’s fault and not ours. I’d recommend the appropriate caution before “blaming the compiler”.

#3Is this title a consequence of some automatic HN system to try to reduce "fluff" in titles? It's kind of nonsensical in this instance. I saw another title earlier today missing a leading "How" that also didn't make much sense.

#4What does that title even mean?

It should read "Your nines are not my nines" which is a little better.

I think HN has some algorithms that attempt to clean up titles to make them less clickbaity, something may have gone wrong here

#7Well, even their nines aren't a whole lot nines if you've been paying attention to all the outages of late.

#8Isn't this why service-level agreements exist? If the nines of uptime are that important to your business and you don't want to be a gnat on a windshield, you've got to give the vendor some financial incentive to pay attention to you, right?
Or is Rachel talking about a situation where you have an SLA in place, but you can't even prove downtime to the vendor because their monitoring software is inadequate?

I think this is about the granularity of SLAs and monitoring.
If a provider promises that, overall, 99.5% of all requests will succeed, but the 0.5% errors are all concentrated on some few customers / regions / AZs, customers can have a very bad day.
So this is about promising each customer that 99.5% of all their requests will succeed, and monitor in a way that makes sure you can keep that promise.

#10The problem is that the vendor is incentivized to publicly use whatever metric shows the highest availability. Otherwise, the vendor will have to pay back credits. The vendor's nines are never my nines.
