Intermittent vs Stable


On what makes an instance Intermittent vs Stable? I mean specifically, not generically?


I am not sure, but I think @thekinrar may be able to answer this question better than I can.
As pulls info from


It looks to me that regularly checks whether the instance is up and down.
Then the uptime ratio is calculated:

hel.upchecks / (hel.upchecks + hel.downchecks)

The fronted treats instances with the uptime ration less or requal 50% as awful, until 95% as intermittent and above that as stable.


Thanks so much @maloki and @saper!
