What is Uptime?

The percentage of time your application is available and working

Why It Matters

High uptime is critical for business reputation and user trust

Real-World Example

99.9% uptime means your site is down for at most about 8 hours per year

“Understanding terms like Uptime matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
