I want uptime modulo in my timezone/work hours. I don't give a shit about any 9's earned while I'm sleeping.

Thanks, never thought about that. Definitely makes sense for situations where you don't have 24/7 requirement for a service.

These stupid SLAs in the SaaS contracts should be reframed like this: 99.9% during working hours, not 99.9% overall. Would also give the SaaS vendor leeway to only guarantee 90% availability outside working hours, and then do their maintenance tasks in those windows.

Sleeping less nowadays...
