Can we stop with the uptime percentages?

The article argues that uptime percentages are increasingly poor communication tools for modern service status pages because non-technical stakeholders interpret numbers like 99.9% and 99.99% as nearly identical, even though the operational difference is significant. For CIOs and technology leaders, the strategic implication is that reliability reporting should be redesigned around business-readable impact metrics—such as hours of downtime or customer-affecting incidents—so IT organizations can communicate risk, prioritize resilience investments, and make service performance understandable across the business.
