Most people who work in Cisco know internally it's a mess. Documents and pages always go missing (404). Our external documentation is also average at best with plenty of mistakes (spelling and technical) and also suffering plenty of broken links.
It's ironic that the best documentation and internal website is the redundancy page. If only we put that much effort into all our products and the things we do.
Good luck all. Unfortunately Cisco is fumbling the future. The old giant became IBM.
