What is Uptime?

Uptime is the period when a website, server or service is available.

Definition

Uptime is the period when a website, server or service is available.

What does it mean in practice?

For websites and online services, Uptime affects response time, reliability, resource usage and the quality of the network path.

A practical Hostilla.pl example

Measure the same URL from a repeatable location before and after a change. Uptime should be correlated with server response time, application logs, resource use, caching and the network path rather than judged from one browser refresh.

What should you check?

  • the exact URL, device, location and test time
  • a baseline for response time and page metrics
  • PHP, database, disk, cache and resource usage
  • one controlled change followed by the same test
