Do you use data to decide if your system has been recently unreliable to your users? What data, and how do you interpret it?

Measuring reliability provided by our production systems has made great strides, and frequently we focus on metrics much closer to the business. But the appeal of now-common metrics like SLI, or models like SLO, can hide our inability to answer our questions with consistent application of data.

This talk will show some questions about reliability we might want answered, discuss the ways we might be coming short today, and how can we improve our ability to make data-inspired decisions going forward.
