On the Ibuildings techPortal blog today there's a new article (a case study of sorts) on how to survive a plane crash. More specifically, a look at how the NU.nl news website handled the load as a result of the crash of a Turkish Airliner.

On February 25th, 2009, less than 90 days after the new infrastructure was rolled out, it was stress tested when a Turkish Airliner crashed at Schiphol. On that day the new site set a single day traffic record by serving up 21 million page views in a 24 hour time period, all without any noticeable slowdown and without having to bring additional hardware online to handle the additional load.

Their framework of choice, CodeIgniter, allowed then to create snippets of content - cached versions - that could be pulled and displayed without having to render them every single time. They looked into the Varnish project and a ATK-based CMS to piece it all back together.
