So, we relied on higher-level metrics-based testing: AB Testing and Sticky Canaries. To determine customer impact, we could compare various metrics such as error rates, latencies, and time to render. We spent the next few months diving into these high-level metrics and fixing issues such as cache TTLs, flawed client assumptions, etc.
