I’m surprised it’s even as high as three nines, at one point in 2025 it was below 90%; not even a single nine.[0] (which, to be fair includes co-pilot, which is the worst of availabilities).

People on lobsters a month ago were congratulating Github on achieving a single nine of uptime.[1]

I make jokes about putting all our eggs in one basket under the guise of “nobody got fired for buying x; but there are sure a lot of unemployed people”- but I think there’s an insidious conversation that always used to erupt:

“Hey, take it easy on them, it’s super hard to do ops at this scale”.

Which lands hard on my ears when the normal argument in favour of centralising everything is that “you can’t hope to run things as good as they do, since there’s economies of scale”.

These two things can’t be true simultaneously.. this is the evidence.

Sure they can. Perhaps a useful example of something like this would be to consider cryptography. Crypto is ridiculously complex and difficult to do correctly. Most individual developers have no hope of producing good cryptographic code on the same scale and dependability of the big crypto libraries and organizations. At the same time these central libraries and organizations have bugs, mistakes and weaknesses that can and do cause big problems for people. None of that changes the fact that for most developers “rolling your own crypto” is a bad idea.
