Kinda. In this context I mean "response SLO" - how much time you have between receiving the page and starting debugging stuff. I think it's also important to clarify; I've been on rotations with response SLO ranging from 5 through 30 minutes to unknown: literally my manager couldn't answer the question "so how fast do you expect me to react" (in hindsight, that was a pretty big red flag about how team approaches production that I missed).
