Hosting reliability
Uptime is the proportion of time a website or service remains available. A strong percentage matters, but monitoring period, maintenance and the application itself all affect what visitors experience.

Period mattersMonthly and yearly differ.
Whole stack countsSite, DNS and database.
What is measured
A monitor requests a page or network service at intervals and records successful and failed responses. Results vary with the test location, frequency and whether planned maintenance is excluded, so compare like with like.
Set a target
For many small sites, 99.9% is a sensible benchmark. Shops, booking systems and critical services may need redundancy, external monitoring and a recovery plan rather than relying on a percentage alone.
Improve reliability
Update software, remove failing plugins, monitor storage and database health, use dependable DNS and keep tested backups. A working server cannot compensate for an application error or expired domain.
