@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 beyond that, the "real GitHub Uptime tracker" captures something important to people "some shit is broken all the time" even if you don't like that they're calling that measure uptime.

@esoterra Yeah, that claim is objectively wrong. One could argue that it would be a good idea to somehow distinguish between "one out of ten subsystems is down" and "the whole thing is completely hosed", but at least "only 100% up is up" is a clear metric without any haggling along the lines of "yeah the web server only said 500 for the last hour but it did ping and receive a mail or two" @yosh
