The PHP toolkit is a powerful feature which if placed on your site, allows the availability checker to be run strictly from your website rather than directing the potential customer to the gigbuilder.com website address. Instead, the toolkit interacts with Gigbuilder on the backend and invisible to the customer! Even better, the toolkit will even check to make sure gigbuilder is accessible, and if not automatically fails over to the backup/secondary mirror gigbuilder server: http://www2.gigbuilder.com! Your availability checker will then work 100% of the time! No more downtime even if the primary site is offline for a reboot!
