Understanding Website Uptime

Website uptime measures the period your site is reachable and functioning correctly. It’s typically represented as a percentage, such as 99.95%, reflecting the proportion of time your site remains online.

While the ideal is 100% uptime—meaning your website is always up and running—occasional interruptions make this difficult to achieve in practice.

What Can Impact Your Website’s Availability?

It’s important to recognize the factors that influence uptime before checking your site’s status. Knowing these can help you address potential issues and enhance reliability after running tests.

Key elements that may affect your server’s uptime include:

• Technical issues: Such as hardware failures or unexpected power outages.
• Human errors: Mistakes made during server updates or routine maintenance.
• Security threats: Incidents like hacking attempts or other cyberattacks.
• Environmental factors: Natural disasters like storms or floods impacting the server location.
• Backup failures: Problems with corrupted backups that don’t restore when needed.

Because of these risks, even the best hosting providers can’t guarantee 100% uptime. Generally, uptime below 99.9% is considered unreliable.
