So then why does no one offer 99.999% uptime guarantees in writing? It should be low risk to offer such guarantees then.

- staticassertion 7mo agoWell, (a) why would they? (b) "uptime" has shifted from a binary "site up/down" to "degraded performance", which itself indicates improvements to uptime since we're both pickier and more precise.
- Alifatisk 7mo agoAre we really questioning why cloud providers would offer better uptime guarantees?
- staticassertion 7mo agoYes, I'm asking why they'd lock themselves into a contract around 5 9s of uptime since the parent poster mentioned that they won't do so. Of course, AWS actually does do this in some cases and they guarantee 99.99% for most things, so it feels a bit arbitrary - 5 minutes vs an hour, roughly.
- MichaelZuo 7mo agoSo then its clearly not as trivial to achieve as you made it sound.
- staticassertion 7mo agoAre you replying to the right person?
- groby_b 7mo agoYou can certainly sign a contract for five nines SLA with cloud providers. You just won't like the price.
- MichaelZuo 7mo agoThen it’s clearly higher risk?
- Anon1096 7mo agoIf you are asking this question you don't understand what it takes to hit 5 nines in a real life measured system.
