Suspicious link in Load Balancer section

[augursem]

In Load Balancer section, under "Source(s) and further reading", the link labeled "Scalability" causes several redirects when I click it (http://www.lecloud.net/post/7295452622/scalability-for-dummies-part-1-clones). I was asked to confirm I was a human by clicking "Allow", referencing a browser popup asking if I wanted to allow the site to run content.
