What’s “website availability?”

Website availability is the amount of time that a website or service can be accessed by users. It is usually calculated as a percentage, and ideally, should be as close to 100% as possible. The “five nines” – or 99.999%, correspond to 5 minutes of downtime per year and is a value worth pursuing.

Why website availability
is important

For most companies, a properly functioning website is a must.
Slow pages and 404 errors can have a major impact on business
and often come with a hefty price tag.

The PRTG Network Monitor provides round-the-clock monitoring
of the performance and availability of your websites. Thanks to
PRTG, you can stop errors in their tracks. And in the event that
one sneaks through, you'll be notified at once.
