For users who have not been able to access the site should check their Browsers as it might be that they are failing our Firewall's Browser Integrity Check. Please check if your PC / Mac is having unwanted programs / malwares / adwares or viruses.
Browser Integrity Check is similar to Bad Behavior and looks for common HTTP headers abused most commonly by spammers and denies access to your page. It will also challenge visitors that do not have a user agent or a non standard user agent (also commonly used by abuse bots, crawlers or visitors).
So if you have any Extensions which modifies the content in any way or automate requests then you need to remove that extension / plugin.
