Site Evaluator - Site Availability

What is the Site Availability metric?

Site Availability measures the percentage of the time that website is up and available to users.

It is critically important that a website be up and responding to users as much as possible. A website that is down is like a store that is closed. Users will not be able to visit, obtain product information, or make purchases. Web sales will stop and users may go to a competitor’s site. While it may not be possible to be up 100% of the time, a site should strive for an availability of at least 99.95%.

How is the Site Availability Score calculated?

When measuring Site Availability, your site is evaluated on whether it is accessible 24 hours a day, 7 days a week, 30 days a month, and 365 days in a year.

Specifically, the Site Availability Score Formula is calculated like this:

• If Site availability is 100%, the Site Availability Score is 100.
• If Site Availability is between 99.91 % and 99.99 %, the Site Availability Score is 70 + (Second digit after the decimal point of Site Availability percentage) * 3.
• If Site Availability is between 95 % and 99.90 %, the Site Availability Score is 50 + (Site availability percentage - 95) * 4.
• If Site Availability is between 0 % and 94.99 % the Site Availability Score is 0 + (Site Availability percentage) * 0.52631578947368421052631578947368.

Site Availability score = (Number of live responses received from the site ping/total number of ping sent to the site) * 100

Availability score	Site availability
>= 70 and <= 100	Good
>= 50 and < 70	Needs improvement
< 50	Poor

How can you improve your site availability score?
