Uptime / Availability
The percentage of time a service is operational and accessible to users.
Uptime measures reliability, often expressed in “nines” (e.g. 99.9%). High availability is essential for trust and retention, especially with business customers, and is frequently committed to via SLAs. Downtime damages reputation and revenue.
Examples
A platform maintains 99.95% uptime. — An outage prompts investment in infrastructure.
