@yosh it's a subtle thing, but I don't like this claim: "A downstream effect of this calculation is that your uptime numbers look worse if your services are well-isolated." if your services are well isolated, meaning an outage in A doesn't cause an outage in B, then that doesn't make you look worse than if they weren't isolated by these metrics, it looks the same. in fact, that they do look the same is their critique.

@yosh ehhhh, each of the component services *also* has only one or two nines -- even if you ignore the dodgy aggregation function, it's not a good situation.

@yosh That post is such a wrird take, as if (additive) uptime measurements aren't a well established standard? It's not even a takedown of the missing status page (which is based on how github used to report uptime, and helped popularize in the industry!) but the author's perception of people's perception of it? Zero nines undegredaded service is still bad. One nine uptime for most subservices is still bad.
