As part of our ongoing commitment to implement new techniques to speed up websites, we are adding http pre-loading and DNS pre-fetch capabilities to non-critical, third-party library files. Previously we were using these techniques to speed up the access for critical BLOX CMS files on our CDN.

This means the browser will attempt to connect to the server as soon as possible, thus minimizing the DNS lookup latency, so the top of the page is available more quickly.
