title: "The hard part of an SLO is deciding what does not count"

description: "An availability SLO for a thirteen-cluster fleet took one query and three decisions about what counts. The decisions were the work, and the denominator hid a service that was completely down."
summary: "The query behind an availability SLO is a one-liner. The decisions about what to leave out of it are the design, and the denominator I chose let a dead service drop out of the number instead of hurting it."
